Process optimisation, part quality, real time control are some key elements for industrial production to be a success.
For dimensional control on grinding machines, the latest system from Marposs includes the new P3ME electronic unit that represents a precise, reliable, economic and compact solution.


  • Parts having small tolerances
  • Avoid effect of grinding wheel wear
  • Operator influence minimised
  • Integration with machine logic
  • Harsh working environment
  • Size controls of parts with restricted access
  • Consistent process
  • Short cycle time
  • Maximum uptime


The P3ME when connected to Marposs measuring heads can position the part and control the part dimensions in various types of grinding machines. The operator can view the analogue meter  and digital display for part status in real time and the set of LEDs  show the signals to the machine control system.
For over 50 years Marposs has understood the grinding machine environment, our range of systems are able to withstand the harsh process while being in direct contact with abrasive grit, metallic particles, cutting oils and aggressive coolants.

This electronic unit is used with UNIMAR, NANOUNIMAR,  MICROALSAR measuring heads.
