For over 60 years Marposs has been the global standard for precision gauging on grinding machines.
The combination of technical know-how in on machine gauging and touch technology has produced the G25 probe, able to do both part surface scanning and touch for part positioning and measurement.
The G25's strong points include compact size, measurement stability at high speeds, allowing for highly reduced cycle times when compared to old point-by-point scanning methods.
The product was developed in order to gauge parts on machines while still fixtured in case rework is required.
The application is composed by a G25 probe and a P32 interface. This system can perform the dual function of:

  • part surface form scanning using an analog voltage output to the machine control
  • touch probe function to be used for part positioning and dimensional measurement

A digital version is also available. This is composed of a G25 probe directly connected to a PC via USB2. Using this layout removes the requirement for the analog to digital conversion in the machine control, because signal is already digitized.

 

Main features:

  • compact size
  • high level of accuracy
  • high touch speed
  • high scanning speed
  • scanning and touch function in all directions (with restrictions along Z axis)

Advantages:

  • scanning and touch function with a single probe
  • part check and positioning inside the machine
  • gear class certification
  • cycle time reduction

Touch and scanning in a single product: this is the G25, the ideal solution for many gauging and positioning applications on machine tools. It can supply a part touch skip signal. Inside its measuring range it supplies a signal proportional to the movement of the stylus on the part, allowing it to be scanned.

G25 probe can be used with different types of styli in order to fit the application specifications. In addition to the vast range of stily available on Marposs catalogue, custom styli can be designed and produced where required.
