Design features

Compact laser optics

  • Compact laser measuring device – the smallest in its class.
  • Smallest tool diameter 25 μm.
  • Accuracy +-0.2 μm.

TCS – true cutting scan for the highest precision


  • Scans the really longest cutting circle.
  • Searches the longest cutting circle diameter.
  • Uses this to the exact length measurement.
  • Correct tool length measurement.


  • Determines the real tool length.
  • High precision length measurement.
  • High-end functionality – exclusively from m&h.

Precision and process reliability

  • Precision measurements of the tool cutting edges at nominal speed.
  • Special supersonic cleaning jet prevents incorrect measurements due to adhering material particles.
  • Software algorithms eliminate the effects of coolant drops.
  • No interference from ambient light.

Applications and measuring routines

  • Measurement of the effective length and diameter with nominal speed.
  • Length compensation of dynamic changes in tool position.
  • Correction of tool length in case of thermal change and thermal drift on the spindle or machine axes.
  • Diameter compensation for dynamic changes in the rotational diameter of a tool.
  • Detection of tool wear and radius compensation.
  • Monitoring of runout, tool change and clamping errors.
  • Tool breakage control.
  • Individual cutting edge breakage control.

Tool cleaning using laval nozzle

  • Laval nozzle with supersonic pressure.
  • Tool cleaning in measuring position.
  • Tool cleaning with nominal rotation speed for optimum cleaning results.
  • Minimal cleaning distance.
  • Sealing cap prevents penetration of foreign objects and liquid.

Pneumatic shutter unit

  • Complete closing shutter unit.
  • Cleaning by air blast without additional air pressure consumption.
  • Air curtain during the measuring process prevents soiling of the optic.
  • Reliable closing after measuring process.

Sturdy design

  • Laser optics protected using shutter unit.
  • Air curtain prevents dirt particles entering the device.
  • Measurement system sealed according to IP68 standard.

Operation suitable for the workshop

  • Simple mounting and setup without special pneumatic unit.
  • Simple orientation and mechanical definition of the focal point.
  • Simple and reliable calibration and setup of the laser unit.
