1. Introduction
Marposs was founded in 1952 and is headquartered in Bologna, Italy. It is a leading global manufacturer of online testing equipment. Its MIDA series CNC probe and tool alignment product line covers multiple fields such as workpiece measurement, tool alignment measurement, tool monitoring, and aperture measurement. In terms of product positioning, Marposs has unique technological accumulation in the fields of lathe measurement and grinding processing, with the WRP series wireless probes and VTS image-based tool setter being its featured product lines.
This article aims to systematically review the product line, technical parameters, and selection logic of the Marposs MIDA series probes and tool presetters, in order to assist equipment selection personnel in matching suitable product solutions based on actual processing needs. The technical parameters are based on the official product manual of Marposs (MIDA product technical manual and D6C series sample).
2、 Overview of Marposs probe technology system
2.1 Trigger Technology
Marposs mainly uses two triggering techniques in workpiece probes:
Kinematic resistance type: Consistent with the commonly used mechanical triggering structure in the industry, precise reset is achieved through three sets of roller ball kinematic positioning mechanisms.. After the measuring needle is subjected to force, it overcomes the pre tension force of the spring and generates displacement, triggering the output signal of the circuit. This structure is mature and reliable, with high reset stability. The VOP60 series (equipped with TT25 measuring needle) adopts this technology, with a repeatability accuracy of 1.0 µ m (2 σ). When equipped with T25 measuring needle, it can reach 0.5 µ m (2 σ).
Piezoelectric sensor type: The Marposs WRP series wireless probe and VOP40P use piezoelectric sensor triggering, which is different from the kinematic structure of traditional mechanical triggering.. The piezoelectric sensor directly detects the charge changes generated by the force on the measuring needle, with a faster trigger signal response and extremely low trigger force (0.07 N), suitable for 3D surface measurement and high-speed scanning applications. WRP45P/WRP60P adopts this technology, with a repeatability accuracy of up to 0.25 µ m (2 σ).
2.2 Transmission Method
Mida VOS optical transmission system: Infrared modulation optical transmission uses coding modulation technology to suppress ambient light interference. A receiver (VOI) can be equipped with up to 4 probes, and two VOS systems can be installed on the same machine to achieve synchronous measurement of 8 probes. The maximum working distance in high-power mode is 6 meters, and in low-power mode it is 3.5 meters. Suitable for small and medium-sized machining centers.
Mida WRS radio transmission system: 2.4 GHz ISM frequency hopping (FHSS) radio transmission, with 79 available channels and 4 sub channels per system. Suitable for large machine tools and five axis machining centers. Supports up to 316 systems running in the same workshop without crosstalk, with a maximum transmission distance of 15 meters.
Hard wire transmission: The T series contact type tool setter, TLS tool setter, and T25P grinder probe all use hard wire connections for reliable signals and do not require batteries. Suitable for workstations where cable routing is convenient and the environment is relatively fixed.
