Diagram of CNC machine geometric errors: pitch, yaw, roll, horizontal and vertical straightness, squareness, and linear positioning

Why and when to check the geometry/calibration of your CNC machine?

  • 01During technical acceptance of a new machine, to confirm the equipment's original accuracy. See an example: the Mazak protocol.
  • 02After relocating or repositioning the machine.
  • 03Before purchasing a used machine, to confirm its performance.
  • 04After a collision.
  • 05Whenever ball screws or rack-and-pinion drives are replaced or repaired.
  • 06When parts fall outside specification — ovality, linear dimensional deviation, squareness errors, or GD&T issues — in serial or non-serial production.
  • 07Periodically, as part of preventive/predictive maintenance.
  • 08After an overhaul or retrofit.

Technical diagnostics, performed directly on your machine

Diagnostics performed to manufacturer requirements or international standards, such as ISO 230 / VDI 3441.

Circularity

Ballbar Analysis

A single circular test reveals geometric, dynamic, and backlash errors, using the same instrument and software recognized internationally as the reference standard.

Linearity

Laser Interferometry

Linearity, squareness, and straightness calibration with internationally referenced precision.

Learn more →
Angle

Autocollimator Measurement

High-precision angular measurement for yaw, pitch, and axis alignment.

Learn more →
Leveling

Electronic Leveling

Correcting transverse and longitudinal twist in ways and guideways before it affects other tests.
