COMP Machine Tool Probe


Machine tool probe COMP series applies 3-point trigger design which is the most stable structure. There is a trigger unit inside the probe. When the stylus is moved radially or axially by external force, the trigger unit is triggered. Then the circuit inside of probe sends a triggering signal to the receiver, and the receiver transmits it to the machine tool, consequently the present coordinates of each axis of the machine tool are recorded automatically. Finally measurement results are calculated according to the coordinate records of related points.


  • Before CNC processing, automatically find the coordinate system and datum point of the workpiece.
  • In CNC processing, automatically measure the key sizes and related coordinates to determine whether compensation is required or not.
  • After CNC processing, automatically measure the sizes, shapes, and positions to qualify finished product.


  • High repeatability: One-way repeatability <1μm
  • Long standby time: As long as 6 months
  •  Omnidirectional energy-absorbing design: 360° omnidirectional energy-absorbing design, which help to cushion the spindle in impact when an operating accident occurs
  •  Waterproof design: IP67 for probe and receiver
  •  Intelligent LED indicators: Show current working status of the probe
