Introduction

Equator relocation and reassembly is a closed-loop process that involves locking the motion platform before transportation, controlling forces and vibrations during transportation, conducting step-by-step acceptance after reassembly, and retesting accuracy with standard components. The core criterion is that the retest results return to within the prerequisite of a comparison uncertainty of ± 0.002 mm. The weight of the 300 machine is 25 kg, and the weight of the 500 machine is 74 kg. The weight is not the difficulty, and the reproducible acceptance chain is the key.

1. Original text: How is relocation defined in official documents

1.1 The official considers “transportation” as an action that requires mechanical configuration

Many device manuals only state one sentence ‘Be careful of shock during transportation’, and then there is no further explanation. Equator is different. The official installation and controller guide (ID 132816) outlines the preparation before transportation as a clear mechanical action: run the “Configure Braking Device for Transportation” to lock the motion platform.

This is not a reminder, but a configuration item. It indicates that the official default understanding is that after a power outage, the motion platform of this machine is not in a self-locking state and must be manually cut into a shape that can withstand transportation loads. This understanding comes from its structure itself.

1.2 Physical limitations of three pole structure

Equator uses a parallel kinematic mechanism, with three linear drive rods (corresponding to P/Q/R axes) and Hooke hinges at both ends. The strut only bears tension and pressure, and does not bear bending moment; The grating is mounted on the strut, and the driving point and feedback point are of the same origin.

The advantage of this structure is that it is light, fast, and has low hysteresis. The official comparison is made between it and the traditional Cartesian structure of “large granite shafts and heavy-duty castings”: the latter relies on large mass to replace rigidity, at the cost of hysteresis and inertia. The other side of the cost is written in terms of transportation – there are no Z-axis pillars, no screws, and no belt transmission, which means that the platform’s posture is completely constrained by the cooperation of the three struts. Once the power is cut off, the collaborative constraint is removed.

So locking before transportation is not about a certain ‘brake’, but about fixing the already determined position, so that the strut does not bear additional alternating loads during transportation. The counterweight balancing mechanism (item 7 in the official component diagram) is also an affected component during transportation, and its internal structure is not officially disclosed. This also determines that it should not be touched or attempted to be disassembled before and after transportation.

1.3 Weight and size determine the level of transportation plan

Model	Overall Weight	Dimensions	Elevated Type
Equator 300	25 kg	570 × 500 × 700 mm	27 kg/height 850 mm
Equator 500	74 kg	1204 × 1139 × 1535 mm	75 kg/height 1685 mm

The 25 kg of 300 can be lifted by two people, but it is still not recommended to carry it directly by hand: the problem is not with the weight, but with the grip position. The 74 kg of 500 has exceeded the range of safe manual handling and requires mechanical lifting or forklift transportation. The external height of 500 is 1535 mm (with an additional height of 1685 mm), the width is 1204 mm, and the depth is 1139 mm – these three numbers determine whether the door width, passage, and elevator car can pass through, rather than the “land occupation” of the machine.

A special reminder is needed for an easily mistaken number: the 300 plus height model has a total height of 850 mm, and its “working volume” has been increased from the base height to 205 mm, but the effective working volume of the Z-axis is still 150 mm, unchanged. 205 mm is not a Z-stroke, so do not consider it as an additional margin when calculating the channel and floor height.

1.4 Storage environment and operating environment are not the same thing

The storage temperature given in the 300 data sheet (H-5504-8251-06-A) is -25~+70 ° C, and the operating temperature is+5~+50 ° C (Chinese specification manual 04-A states+10~+40 ° C, which belongs to the old version caliber, and the following single version shall prevail). **The working environment humidity condition is ≤ 80% RH at 40 ° C, non condensing; The official data table for storage environment humidity is not listed separately and should be treated according to non condensing requirements.

The significance of these two intervals is that the environmental range allowed for machines in packaging boxes, warehouses, and carriages is much wider than their working state, but * * width does not mean that they can be placed randomly. -25~+70 ° C is the storage limit, not the recommended value; Non condensing is a hard condition. Once condensed water enters the controller, the official disposal is to cut off the power, not to power it back on, and return it to the supplier for replacement, which is not within the scope of warranty and service.

Why should it be referred to as SOP instead of “precautions”

‘Precautions’ is a series of independent sentences that only reveal the risks after reading, without knowing which step to take first or how to calculate after completion. Each step of SOP involves input, action, and acceptance. If the previous step is not passed, the next step will not be taken.

The particularity of relocating and restoring a machine lies in the fact that almost all actions are irreversible or costly: turning off the power and then turning it back on may expose hidden faults, removing the fixture board and reinstalling it may change the clamping reference, and using an old master may mistake system errors for machine errors. The cost of correcting mistakes after making them is much higher than spending an extra two hours beforehand.

So this article is organized according to the principles of “first criterion (Chapter 2), then numbering steps (Chapter 3), then boundary drawing (Chapter 4), and finally providing the first inspection record form that can be directly printed and filled out (Chapter 5)”. If readers only want to take one table, they can skip directly to Chapter 5.

There is another practical reason: Equator’s accuracy statement is based on a comparison uncertainty of ± 0.002 mm, rather than absolute accuracy. This indicator has three prerequisites – immediate measurement after re mastering, clamping position difference of parts relative to standard parts ≤ 1 mm, and use of certified standard parts. The relocation has simultaneously disturbed the physical foundations of these three conditions: the pose has changed, the clamping reference may have changed, and the state and position of the standard parts have also changed. So ‘restoring accuracy after moving’ needs to be translated technically as’re meeting the three conditions that make ± 0.002 mm valid ‘. This is also the reason why this article lists the pre migration values in a separate column: without pre migration values, it is impossible to distinguish between “restored” and “just like this”.

2. Criterion layer: threshold, official basis, and measurement method for each step

2.1 Pre transportation criteria: sequence of locking, power-off, and disassembly

Order is the most easily reversed term in hard criteria. The correct sequence is: Lock the motion platform first, then turn off the power, then remove the fixture board, and finally disconnect the wire.

Why locking must be done before power outage. Locking is a configuration action that needs to be completed through a controller or mechanism, and there is no execution path after power failure; If the power is cut off first and then attempted to lock, the actual operation will become manually pushing the platform to find the position, which is exactly what the transportation manual does not want to happen.

Why is it necessary to dismantle the fixture board after power failure and before disconnection. Fixture board (300 is a 305 × 305 mm aluminum plate, with 41 holes M6/M8/¼ “, optional 441 holes; 500 (510 × 510 mm) itself is a disassembly component, and disassembling it requires contact with the platform surface. Power off is to prevent any misoperation from driving the shaft; Breaking the wire after dismantling the board and exposing the platform is to avoid the cable tripping the platform during dragging.

The order of disconnection is: first disconnect the signal and interface lines (including EQ-IO interface unit REN-IO, Disconnect the main power line after the automation online line is connected. The reverse problem is: first disconnect the main power supply, the controller still has residual charge and cache state, and unplugging the signal line at this time may cause the interface unit to power off at abnormal levels.

2.2 Lifting criteria: starting points and prohibited force bearing parts

The key criterion is not ‘where to focus’, but’ where is the load-bearing structure ‘. The structural components provided in the official component diagram are: base casting, top casting, drive strut, support strut, upper pivot/hook hinge, support arm, drive cover, parallel constraint mechanism, counterweight balance mechanism, fixture plate, and stop button.

Parts that can withstand force: integral castings such as base castings and top seat castings, as well as reserved positions for lifting (subject to random documents).

Parts that cannot withstand force:

Drive strut: It only bears tension and compression. Once pulled or subjected to lateral force, it will introduce bending moment, and the hinge part is the first to be damaged;
Orange Shield/Drive Housing: The shield is a protective component, not a load-bearing component;
–Support rod and support arm: They are part of the constraint chain and will change the constraint when subjected to force;
–Weight balancing mechanism: The internal structure is not disclosed, and any external force intervention may disrupt the balance state;
Mobile platform itself: The platform is a moving part, not a suspension point.

The implementation method of this criterion on site is very simple: draw the path of the sling before lifting, and for anything that needs to pass through the strut or protective cover, change the route; If it is unavoidable, add padding and only allow contact, not tying.

The verification of the transportation channel is calculated based on 1204 × 1139 × 1535 mm (with a height increase of 1685 mm) of 500. It is recommended to reserve a margin of 50-100 mm on one side according to industry practices, plus the thickness of the packaging box and the height of the pallet. The height of the door opening, the width of the elevator door, the turning radius, and the ground bearing capacity should all be measured, not just the width of the door. The height of the forklift entering the fork and the clearance between the pallet and the ground should also be confirmed to avoid “passing the door and not entering the elevator”.

Why are these four numbers: 500 with a height of 1535mm, often exceeding two meters with pallets and packaging, and the height of the door opening is the first checkpoint; The width of 1204 mm is the machine body, which is usually widened by about 200 millimeters after packaging. The width of the elevator door is the second checkpoint; The depth of 1139 mm determines the turning and sweeping space, and right angle turns at the end of the corridor are the most common failures; The load-bearing capacity of the ground is related to the floor slab and ramp. If any of the four routes fail, the plan needs to be changed, and the cost of changing the plan will sharply increase after the equipment is installed.

Another rule: Channel verification should be done before placing an order or signing a contract. This is especially true for second-hand equipment, as the transportation cost and risk of returning the machine once it is out of stock are borne by the buyer.

2.2b Dynamic criteria during lifting process

In addition to the static lifting point, there are two dynamic criteria during the lifting process.

The first one is tilting. The inclination after leaving the ground reflects whether the length of the suspension cable is symmetrical and whether the center of gravity falls within the surrounding area of the suspension point. Excessive tilt means that some of the load has been transferred to areas that should not be subjected to force. At this point, it is not advisable to ‘lift it up a little bit’, but to lower it back to the ground and rearrange the cables.

The second one is abnormal noise and crawling. If metal friction or jamming is heard during lifting, or if there is relative displacement between the box and the machine, it indicates that the internal fixation has failed or the sling has contacted the prohibited force area. The criterion is’ no sound throughout the entire process, no displacement ‘. If any phenomenon occurs, immediately place it and follow the’ 100 mm off the ground inspection ‘procedure.

2.3 Packaging criteria: shock resistance, moisture resistance, and posture

Shock resistance: The biggest risk during transportation is not falling, but resonance and continuous vibration. The sensitivity of the strut system to low-frequency vibrations decreases in the locked state, but a damping layer is still required. The criterion is that there is no hard contact point between the machine and the box, and there should be no gap left in the lining for the machine to move inside the box.

Moisture proof: Non condensing is a hard condition. Desiccants should be placed and sealed for long-distance, cross climate, and sea transportation. The criterion is that there are no traces of condensed water, no odor or mold when opening.

Attitude: Transport according to the default posture configured by the official transportation system, do not place sideways or upside down. 500 up to 1535 mm, with a high center of gravity, must have anti overturning bottom fixation during transportation.

Fixed method: Rigid fixation (bolts or specialized brackets) is used between the base casting and the tray, and the box is tied to the carriage. The criterion is’ pushing the box by hand without moving ‘, and there is no displacement during driving.

2.4 Reinstallation Criteria: Acceptance Actions for Each Step

Reinstalling is not about ‘putting it back’, it’s about ‘gradually building trust’. Each step should have an action that can be judged on the spot whether it passes or not.

Steps	Actions	Acceptance Criteria
1. Mechanical positioning	Position to the designated location, inspect appearance	No transportation damage, no cracks in castings, no deformation of protective covers, and no scratches on struts
2. Leveling and foundation	Leveling, foundation force	Platform level meets the requirements of the random file (based on the official data sheet), and the four corners are evenly stressed
3. Reinstall the fixture plate	Reinstall the fixture plate and insert	No warping, securely fasten in place, and align the holes; The clamping standard is consistent with before moving
4 Wiring and Power on	Follow the timing sequence in Step 15 of Section 3 for wiring	No alarm, controller starts normally, and license is valid
5. Needle changing frame positioning	If an automatic needle changing frame is configured, execute EQR-6 positioning Part 1/Part 2	Both steps pass, and the positioning result is accepted; If there is no automatic needle changing rack, skip and indicate
6 Calibration	Calibrate according to the comparison process	Generate `.CAL` and streamline the process
7 Mastering	Mastering standard parts	Clamping position difference ≤ 1 mm, standard parts with certificates, Mastering completed
8 pieces retest	Compare with known pieces	The results are consistent with the pre move records and fall within the expected range

There is a non interchangeable order: EQR-6 positioning must be done before needle change. After the needle changing rack is moved, its position in the machine coordinate system changes. If the needle is not repositioned, it will be grabbed, and the positioning of the stylus will inevitably have a deviation, which will be misread as a problem with the probe or stylus.

2.5 First inspection criteria: which ones are energetic and which ones can only be qualitative

For each item of the initial inspection, either numerical criteria are given, or “official data sheet shall prevail” is written, or qualitative criteria are given (no abnormal noise, no cracks, smooth entire travel). All three are legal, but it cannot be written as’ based on experience ‘. Please refer to Step 15 in Section 3 for the wiring sequence.

Items that can provide official values: storage and working temperature, humidity, power specifications, comparison uncertainty ± 0.002 mm (based on three preconditions), probe deflection ≤ 4 μ m, clamping position difference ≤ 1 mm.

Unofficially quantified items: specific indicators of leveling, foot tightening torque, fixture plate tightening torque, and quantified values of strut clearance. All of these should be written in the text as’ based on official data sheets/manuals’ or given qualitative criteria, without fabricating torque and clearance values.

2.6 Priority of Criteria: Which criterion should be considered first when encountering problems

After relocation, if the accuracy is not correct, the order of investigation should be prioritized according to the “process with the greatest change”: mechanical positioning and leveling (overall posture has changed) → fixture board installation (clamping reference has changed) → needle changing frame positioning (needle changing position has changed) → calibration and mastering (related relationship has changed) → environment (temperature gradient has changed).

The principle of this sequence is that the earlier the links, the more errors will affect the overall situation; The later the link, the narrower the impact range. Starting from the probe, it is often found that the machine has not been leveled after a round of inspection.

2.7 Writing Rules for Criteria: Three Expressions, One Prohibited

When writing the initial inspection form, each criterion can only fall within one of the three valid expressions.

The first type is the official numerical value.Directly write numbers with publicly available sources and indicate the range, such as storage temperature -25~+70 ° C, comparison uncertainty ± 0.002 mm, probe deflection ≤ 4 μ m, clamping position difference ≤ 1 mm.

The second type is officially undisclosed quantitative indicators.Write ‘According to official data sheet/manual’ and clearly indicate the verification path in the remarks (which random file and section to check).

The third type is qualitative criteria.Describe with observable phenomena, such as’ no cracks in the casting ‘,’ smooth throughout the entire process, no abnormal noise, no crawling ‘, and’ no self sliding after stopping ‘. The qualitative criteria are not ambiguous, and two individuals can independently determine the same result.

**One of the prohibited values is the experience circle integer: leveling 0.02 mm/m, torque 8 N · m, gap 0.05 mm. These numbers may seem professional but have no source, and cannot be self verified when questioned. If they are written into the table, they will be cited as specifications by downstream.

If there is indeed an experience threshold within the customer, a separate column labeled “Enterprise Internal Control Value” should be set up, separate from the official parameter column. Coexistence of two columns is not a problem, mixing them into one column is.

3. Disposal layer: numbering steps and safety tips

3.1 Stage 1: Before transportation (it is recommended to leave half a day)

Step 1 | Confirm the status before power outage.Before locking, record the current status: software version, license form (license key file or USB dongle), mastering record, .CAL file, measurement program, and the latest comparison result. This record serves as a reference baseline for the re inspection of the equipment. Without it, the table in Chapter 5 would not have any ‘pre relocation values’ to fill in.

Step 2 | Run ‘Configure brake device for transportation’.Follow the official installation and controller guide (ID 132816) to lock the sports platform. The acceptance criterion for locking is that after the institution enters the transportation configuration, the platform is no longer driven. After locking, do not push the platform to verify if it is locked, as this action itself is a risk.

Step 3 | Power off.Exit the software through the normal shutdown process and then disconnect the main power supply. Do not directly unplug the plug.

Step 4 | Remove the fixture board and accessories.Fixture board, needle changing rack (300 comes with a six position needle changing rack; X-500 is clearly EQR-6; 300/500 (based on order configuration), measuring needles, standard parts, workpiece temperature sensors (WPS-2 for X-500), etc. are all items that must be individually packaged. Different reasons: The fixture board is a precision flat component, and transporting it together with the machine can easily cause damage from other components inside the box; The stylus and needle changing frame are afraid of collision, and once the stylus ball is damaged, the error is irreversible; Standard parts have certificates, and collisions can cause the certificates to become invalid, leaving no reliable benchmark for comparison when restoring the machine.

The individually packaged items should be numbered, photographed, and aligned with the packing list. In second-hand equipment transactions, missing attachments are the most frequent source of disputes, which can be avoided with just a packing list.

Step 5 | Disconnect the wire.First signal line (EQ-IO interface unit REN-IO, Automation online), rear power cord. The cables are individually coiled and marked, and should not be confined between the machine and the box wall.

The packing list also has criteria: the part number must correspond one-to-one with the actual item, and cannot just write “number of measuring needles”. Copy the spare part number on the label before packing, as this is the only thing that can prove ‘all original documents are present’ when the machine is returned and transferred three months later.

Step 6 | Packaging.The vibration reduction layer, moisture-proof layer, bottom rigid fixation, and box binding are completed in sequence, and a “pushing the box without moving” test is conducted.

3.2 Stage 2: Lifting and Loading (Safety First)

Step 7 | Channel Review.Verify the load-bearing capacity of door openings, elevators, bends, and floors using 500 pieces of 1204 × 1139 × 1535 mm (with a height increase of 1685 mm), packaging box thickness, and pallet height. The 570 × 500 × 700 mm (with an additional height of 850 mm) of 300 also requires packaging thickness.

Step 8 | Lifting.Use lifting equipment with a surplus of rated load (the surplus ratio shall be subject to the on-site lifting specifications). The sling is only allowed to contact the designated position of the base or top casting, and it is prohibited to wrap around or pull the drive strut, orange shield, or support strut. Suspend and check the force and tilt once after lifting about 100mm off the ground, confirm that there are no errors, and then continue.

Step 9 | Install and fix the vehicle.The box body is tied to the carriage, and the bottom is anti slip to avoid forward and backward movement. 500 center of gravity high, side limit must be implemented.

Safety reminder: No one is allowed to stand on the transport channel; No one is allowed under the lifting operation; The actions related to the counterweight balancing mechanism are not within the scope of relocation operations, and do not attempt to disassemble or adjust them at any time.

3.3 Stage Three: Arrival and Reinstallation (Acceptance in Step by Step Following the Order of Section 2.4)

Step 10 | Unpacking inspection.Check the packaging, box for condensation, machine appearance, castings and shields, and strut surfaces. If any scratches are found, they should be photographed and recorded, and the position and size should be clearly stated on the appearance line of the first inspection form. This line is the main basis for subsequent disputes.

Step 11 | Mechanical positioning.Position at the designated location, leaving space for operation and heat dissipation around (specific distance subject to random file). During the positioning process, it is still not allowed to use struts or shields as leverage points.

Step 12 | Release the transportation lock.This step is executed in the order of “Release Transport Configuration” in the official installation guide, which is a symmetrical action with locking. After release, the platform will return to a drivable state. Do not run any measurement programs until leveling is completed.

Step 13 | Leveling and foundation.Leveling and evenly distributing force on the four corner feet. This is the first action that affects the entire system after the machine is restarted. Starting the test without leveling is the most common type of machine relocation accident.

Step 14 | Reinstall the fixture board.Reinstall the fixture plate and insert, confirm that there is no warping and the hole positions are aligned. Whether the clamping benchmark is consistent with before moving shall be confirmed by the first piece retest.

Step 15 | Wiring and power on timing.The sequence is opposite to power-off: first connect the main power line, then connect the signal and interface lines. After powering on, confirm that the controller starts normally, there are no alarms, and the license is valid.

Step 16 | Needle exchange holder positioning (Part 1/Part 2).First, confirm whether the machine is equipped with an automatic needle changing rack (X-500 is clearly EQR-6300/500 according to the order configuration); If configured, the needle changing rack has changed position during transportation and must be repositioned. Both Part 1 and Part 2 must pass before entering the needle changing test, and must be completed before any needle changing action. If the automatic needle changing rack is not configured, skip this step and indicate it on the initial inspection form.

Step 17 | Calibration.Follow the comparison process used before moving (one of the four types: no calibration/CMM calibration/calibration/tolerance calibration) to generate .CAL, and do not easily change the process.

Step 18 | Mastering.Mastering with certified standard parts. The three prerequisites are met simultaneously: immediate measurement after re mastering, clamping position difference of each part relative to the standard part ≤ 1 mm, and certification of the standard part.

Step 19 | First article retest.Retest the known items recorded before moving and compare them with the pre moving values. This step marks the end of the entire chain and results in the table in Chapter 5.

3.4 Methods for verifying needle change consistency

After moving the machine, the deviation of needle changing position is the most hidden problem. The method is to use two calibrated measuring needles (or the same stylus installed on two needle changing positions) to measure the same standard feature and compare the two sets of readings.

In terms of criteria, the official did not provide an independent indicator for needle change consistency, only stating that ‘the official data table shall prevail’, but the judgment logic is executable: the difference between the two sets of readings should be explained by the calibration value of the stylus and the deviation of the probe ≤ 4 μ m; The difference is much greater than this, first recheck the EQR-6 positioning, and then check the stylus.

3.5 Additional handling for long-distance transportation

Transportation across provinces and climate zones carries two additional risks: condensation caused by temperature and humidity cycling, and prolonged continuous vibration. Solution: Place a humidity indicator card inside the box (the reading can be directly used as evidence when opening); If the transportation time exceeds several days, check and tie it up midway; After arriving, do not immediately turn on the machine. Let the machine stand in the workshop environment until it is at the same temperature as the environment before powering it on to avoid condensation.

4. Boundary layer: Under what circumstances should one not move on their own

4.1 Belongs to actions that can be completed independently

The boundaries of the actions that can be completed by oneself in the relocation and restoration of the machine are very clear: power-off and disconnection, disassembly and assembly of fixture plates, lifting and positioning, leveling and anchoring, EQR-6 positioning according to the interface, calibration and mastering according to the process, and first inspection recording and judgment. These are all operational actions, and the official documents have clear steps.

Cleaning maintenance can also be completed by oneself: cleaning kit A-5504-9055 (including spare dust filter, prohibited cleaning agent), controller fan filter A-5696-0120 (12 piece set, replaced in high pollution environment for 6 months), and probe inspection.

4.2 Actions that must be stopped or changed in disposal methods

Once the following situations are encountered during the relocation and restoration process, self disposal should be stopped:

Structural components are damaged.Casting cracks, strut collision deformation, and shield compression deformation. This type of problem will affect the constraint chain and self correction is not feasible.

The counterweight balance mechanism is abnormal.The official has not disclosed its internal structure, and any dismantling or adjustment is not within the scope of self completion.

The linear encoder scale body is scratched.The grating is mounted on the strut, and the driving point and feedback point are of the same origin. The damage to the body cannot be solved by cleaning, it belongs to the situation that requires the original factory calibration process.

Enter the liquid.The official disposal is clear: power must be cut off, cannot be re powered on, return to the supplier for replacement, not within the scope of warranty and service. The most expensive mistake is’ wipe dry and try to open ‘.

License and encryption upgrade package issues.The license comes in two forms: key file and USB dongle. The upgrade package is encrypted and requires version verification. The startup failure caused by license migration and version mismatch requires going through the original factory process.

4.3 Correct understanding of “controller without user repairable parts”

The official original text is: There are no user repairable components inside the controller. This sentence constrains the device user, indicating that the official will handle the replacement as a whole.

This statement does not mean that ‘if the internal components are damaged, the entire machine can only be replaced’. Third party professional maintenance can perform board level and component level repairs, covering power modules, driver boards, interface boards, connectors, fans and filters, storage media, cables – this is not contradictory to the official statement, which restricts users from repairing on their own, not professional maintenance providers.

But the three boundaries must be clearly stated at the same time:

Non original factory repairs will void the original factory warranty for the component, which must be clearly explained and confirmed to the equipment owner before starting work;
After repair, it is necessary to re verify, including accuracy, safety circuit, and license availability. Missing one item does not count as complete repair;
In cases of structural deformation, scratches on the linear encoder scale body, or the need for original factory calibration or encryption upgrade package/license migration, it is still recommended to follow the original factory service process. **

4.4 Additional Risk List for the Landing of Second hand Equipment

Bosses who buy second-hand machines have four different risk points compared to those who move their own machines:

Is the transportation lock correctly executed.It cannot be confirmed afterwards whether the “brake device configuration for transportation” was run during the previous disassembly. The criteria can only be indirectly examined: whether there are abnormal wear marks on the surface of the strut, whether there are displacement marks at the hinge, and whether the platform is smooth and free of jamming points throughout the entire stroke. If any abnormalities are found, they should be treated as structural damage first.

Is the grating contaminated.Machines that have been parked for a long time are prone to dust and oil accumulation on the grating and reading head on the support pole. Clean your hands first (using the official cleaning kit, with no cleaning agents), and then check if the readings and signals are normal.

Is calibration and licensing included with the machine.There are two forms of licenses, whether the dongle is delivered with the machine and whether the key file can be migrated, both need to be confirmed before the transaction. A mismatch between the software version and the upgrade package version can directly lead to startup failure.

Are the random attachments complete.Standard parts (benchmark), measuring needles, fixture plates, needle changing racks, cleaning kits, and random files are all essential components. The most troublesome issue is the lack of standard parts: without certified standard parts, mastering loses its benchmark, and the uncertainty of ± 0.002 mm comparison cannot be discussed.

The replacement path follows the order of “confirming the order configuration first, and then supplementing according to the official spare part number”: there is usually an order configuration list in the random file, and the missing items are checked according to the list; The stylus should be selected according to the official sample (SM25 module has three types: SM25-1 short stylus 20-50 mm, SM25-2 straight rod 50-105 mm/curved rod ≤ 83 mm, SM25-3 longest 200 mm), and should not be matched based on appearance. Attention should be paid to compatibility when triggering the probe: A-5504-0070 is compatible, A-5504-0065 is not compatible. It is recommended to trigger at a speed of 10 mm/s.

4.5 Suggestions on Responsibility Allocation for Relocation Projects

Moving involves three parties: equipment user, moving company, and technical service provider. It is best to clearly define the responsibility boundaries of the three parties before starting construction, otherwise there will be a dispute over who caused the damage when problems arise.

Suggested division of labor: The equipment user is responsible for recording the status and counting accessories before power failure; The moving company is responsible for lifting, loading, transporting, and unloading, following the requirements for non stressed areas and fixing; The technical service provider is responsible for unlocking, leveling, reinstalling, positioning, and calibrating mastering, First inspection.

The key to division of labor is that the status record before power outage must be completed when all three parties are present. It is both a technical baseline and a responsibility baseline. Without it, all disputes about whether it was like this before moving or only after moving cannot be resolved.

There is another easily overlooked link: temporary storage after unloading. The machine is placed in the workshop waiting for installation window, and this period is also considered storage. The temperature and humidity must meet the storage requirements of 300 (-25~+70 ° C, non condensing), and cannot be placed outdoors, near external walls, or in areas with condensation water.

5. Verification layer: First inspection record form and acceptance judgment

5.1 First Inspection Record Form (can be directly printed and filled in)

Usage of the table: On the left side of each row is the criterion, the measured value is left in the middle, and the judgment is left on the right side. The judgment column only allows three values – qualified, unqualified, and based on the official data table (when no random file is obtained). It is not allowed to write ‘approximately qualified’.

Serial number	Inspection item	Criterion (reference value/qualitative requirement)	Actual measurement value	Judgment	Pre moving value/Remarks
1. Appearance and Structure: The casting has no cracks, the protective cover has no deformation, and the strut has no scratches; Transport damage location recorded			Photo for record keeping
2	Level (Leveling)	Meet the requirements of the random file (based on the official data sheet); Have the four corner feet been uniformly stressed before moving
3	Fixture board and embedded parts	No warping, hole alignment, and secure in place		Torque according to official manual
4	Power on and zeroing	The controller starts normally, there are no alarms, and the platform can be driven; Return to zero completed			Record alarm number
5	Single point repeatability	Multiple touches on the same point, with dispersion within the expected range (based on official data table and pre move records)			Compare the same caliber values before moving

Three rules for filling out forms: Firstly, the measured values shall not be copied across rounds, and shall be retested every round; Secondly, lines 5, 6, and 7 must be filled with ‘pre migration values’. If there are no pre migration values, this round can only serve as a new baseline and cannot be used as proof of’ restoration accuracy ‘; Thirdly, any non-conforming items must have corresponding disposal records, and cannot be terminated simply by writing “non-conforming” in the judgment column.

5.2 Three actions after judgment

If the first inspection fails, there is no need to immediately sentence to death. Divided by conduction chain:

The first step is to rectify on-site.Issues related to configuration and status: leveling not done, fixture board installation deviation, EQR-6 needle replacement without positioning, mastering using old values, .CAL not compatible with the program, license not activated. These actions can be restrained on site, just run the corresponding steps again.

Second tier, limited use.There is a deviation in accuracy but the function is normal, for example, the retest of the standard part in line 6 falls in the critical zone. At this point, the usage conditions should be tightened (limiting the range of workpieces and measuring types), and clear shutdown triggering conditions should be set instead of using as usual.

The third level is professional disposal.Damage to structural components, abnormal grating, controller failure, and permission migration issues. This one can either undergo board level maintenance (and bear the boundary of warranty failure and need to be rechecked), or go through the original factory process.

5.3 How to consider the re machine acceptance as completed

The definition of completed acceptance is: All 12 lines have a judgment, and the 5th, 6th, and 7th lines are comparable to the pre move values.Missing any line is not considered complete.

There is a common self deception here: just do the fourth line (power on and return to zero is normal) and declare the restart complete. Normal power on only proves that the electrical circuit is connected, and has nothing to do with accuracy. On the other hand, it is not enough to declare completion just by doing the 6th line (passing the retest of the standard part) – if the retest of the standard part passes without checking the consistency of the needle change, the deviation of the needle change position will appear in the form of “drift of the result after needle change” in actual production, and half a day of production capacity has already been ruled out.

5.4 Record retention and next relocation

After filling out the initial inspection form, at least three copies should be kept: one should be archived with the machine, one should be submitted to the equipment supervisor, and one should be included in the project file. The pre relocation values on the table are the benchmark for the next relocation. When relocating for the second time, the “pre relocation value” column should be filled with the result of this time, so that there is comparability between the two rounds.

The value of the first inspection form is not on the day of acceptance, but three months later. When the customer says’ recently the measurements were not very accurate ‘, the only comparison that can be made is this table – it turns the vague feeling of’ accuracy ‘into a series of numerical values with dates.

5.5 Typical combinations and directions of initial inspection failure

One of the values of the first inspection is the “combination reading method”: if a single line is not qualified, the direction is unclear, and looking at several lines together can often pinpoint the cause.

Phenomenon combination	Most likely cause	Where to investigate first
The second and sixth lines are both unqualified	The overall posture is not leveled, or the force on the foot is uneven	Leveling and foot, repeat step 13
Line 6 is not qualified, line 5 is normal	There is a problem with the clamping reference or standard parts	The fixture plate is reinstalled, and the clamping position difference is ≤ 1 mm, and the standard part certificate
Line 5 unqualified, Line 6 critical	Abnormal mechanical state or strut constraint	Whether the strut action is smooth and whether the transportation lock has been released
Line 7 is unqualified, line 8 is normal	Needle replacement positioning is not done or there is a problem with stylus clamping	Redo EQR-6 positioning Part 1/Part 2
Lines 5, 6, and 7 are not qualified at the same time	leveling has not been done, or the old mastering has been used	leveling, and then recalibrate with the mastering
Line 9 Unqualified	License or version issue	License form (key/dongle), version matching
Line 4: Unqualified	Power on timing, cable, or transportation damage	Wiring sequence, whether the cable has pressure damage, alarm number

The usage of this comparison table is’ first look at the combination, then look at the single row ‘. Its significance lies in translating the general judgment of ‘inaccurate accuracy’ into a troubleshooting path that can be executed sequentially, reducing unnecessary disassembly.

5.6 The first week after resuming operations

After the re acceptance of the equipment, there is still a period of observation worth arranging. The reason is that some of the state changes introduced by relocation will not be exposed on the day of the initial inspection, but will become apparent after a period of use, such as loosening of fasteners after vibration and temperature cycling, poor contact of cables after frequent initial movement, and slight sinking of the foundation after stable load.

The method is to arrange two random inspections within the first week: one on the second or third working day after resuming operation, repeating lines 5 and 6; At the end of the first week, repeat lines 6 and 7. Having passed both times, it can be considered that the state is stable; Drift occurred just before it affected production.

This observation period is often omitted because the project is considered closed after the acceptance form is signed. The signature only proves the status at that moment, and the observation period only proves the sustainability of the status.

Frequently Asked Questions (FAQ)

Q1: Can the transportation lock be skipped and the machine can be directly loaded onto the truck?

Not recommended. The official installation and controller guide (ID 132816) explicitly requires the operation of “configuring braking devices for transportation” to lock the sports platform, which is not an optional prompt. The reason lies in the structure: the three straight driven struts only bear tension and compression, and the platform posture relies on the collaborative constraint of the three struts. After power failure, the collaborative constraint is removed, and the vibration and impact during transportation will directly act on the struts and Hooke hinges. The short-term consequences cannot be seen, while the long-term consequences are changes in the force characteristics of the strut, manifested as unstable accuracy. Second hand equipment cannot confirm whether the previous operation was carried out, and such risks can only be predicted based on structural damage.

Q2:500 The whole machine weighs 74 kg. How many people can lift it?

It is not recommended to use manual lifting, mechanical lifting or forklift transportation should be used. The problem is not only with the weight of 74 kg, but also with the gripping position: most of the places on this machine that are convenient for gripping are the drive strut, orange shield, and strut, and these parts are not allowed to be subjected to force. The inability to precisely control the point of force when lifting a person is equivalent to putting the prohibited force bearing area at risk. When lifting, the sling is only allowed to contact the base or top casting and the designated lifting position. The path should be drawn in advance, avoiding the strut and protective cover. The 500 has a height of 1535 mm (with an additional height of 1685 mm), a high center of gravity, and must prevent overturning during lifting and loading.

Q3: If the leveling is not restored after moving, how much difference will it make if measured directly?

The difference depends on the transportation and positioning process, and the official has not given this number, so it cannot be compiled. But it can be confirmed that starting the test without leveling will treat the overall pose error as a machine error, and such errors will occur simultaneously in the retesting of standard parts, single point repeatability, and needle change consistency, and the direction of investigation will be biased. What’s even more troublesome is that if mastering is done again at this point, the correlation between the standard parts and the machine coordinate system is established on the wrong pose, and all subsequent comparison results carry this offset. Leveling should be done in step 13 of the reassembly sequence, and no measurement program should be run until leveling is completed.

Q4: Can the mastering records of old machines still be used?

No. Mastering establishes the correlation between standard parts and the machine coordinate system, relying on the actual pose of the machine, the fixture board clamping reference, and the needle changing frame position – the moving machine happens to change all three things at the same time. The consequence of using the old mastering is that the deviation caused by pose changes is mixed with the deviation of the machine itself, and the error is masked rather than discovered. The correct approach is to re master after reassembly, meeting three prerequisites: immediate measurement after re mastering, clamping position difference of parts relative to standard parts ≤ 1 mm, and certification of standard parts. Old records are not useless, their purpose is to compare values, not run values.

Q5: What problems will occur if the needle is changed without EQR-6 positioning?

There will be a drift in the results after changing the needle, and it is extremely difficult to locate. After the needle changing rack is moved or disassembled, its position in the machine coordinate system has changed, and there is a deviation between the actual position of the stylus and the position recognized by the software. This deviation will not appear in the form of an alarm, but will manifest as different results for the same feature measured by the same stylus before and after needle replacement, or an overall deviation in the comparison results after needle replacement. The easiest misjudgment on site is to attribute the cause to the stylus or probe, so dismantle the stylus, replace the stylus, check for deviation, and circle back to the origin. The order cannot be reversed: relocate EQR-6 (Part 1 and Part 2), replace the needle, and perform consistency verification again.

Q6: Which accessories are the most deadly when buying a second-hand machine?

Missing standard parts are the most fatal. It is the benchmark for comparative measurement. Without certified standard parts, there is no reliable reference for mastering, and the uncertainty of ± 0.002 mm in comparison cannot be discussed – one of the three prerequisites is the use of certified standard parts. The second fatal aspect is licensing: there are two forms: license key files and USB dongles. Whether the dongle can be delivered with the machine and whether the key can be migrated must be confirmed before the transaction. The stylus, fixture board, needle changing rack, cleaning kit, and random files are replaceable parts. The stylus should be selected according to the official stylus sample SM25 corresponding specifications, and should not be matched according to appearance.

Q7: After the machine is moved and powered on normally, is it considered that the restart is complete?

Not counted. Normal power on only proves that the electrical circuit and controller are in normal condition, and is not related to accuracy. The definition of the completion of re testing is that all 12 rows of the initial inspection table have judgments, and the single point repeatability, standard part re testing, and needle change consistency are comparable to the pre moving values. This definition corresponds to the four things that relocation truly changes: posture, clamping reference, needle changing position, and related relationships, which are precisely covered by these three tests. Simply confirming power on before production is equivalent to delaying the exposure of risks until the first batch of workpieces are scrapped.

Q8: The machine may have been exposed to moisture during transportation, can it still be powered on?

You can’t turn on the power just because it looks dry. The official handling of liquid intake is clear: power must be cut off, cannot be re powered on, return to the supplier for replacement, and is not within the scope of warranty and service. To determine moisture, three pieces of evidence should be examined: the reading on the humidity indicator card inside the box, the presence of condensation marks on the box wall and machine surface, and the presence of water stains or mold around the controller air inlet and fan filter (A-5696-0120). If there is any evidence, treat it as damp and do not dry it before powering on. Prevention is to do a good job of moisture-proof during the packaging stage: sealing, desiccant, humidity indicator card. The cost is very low, but it is the only thing that can clarify responsibility afterwards.
