Koma Precision Calibration


Koma Precision now offers laser calibration for multi-axis mills and lathes.

We’ve added the industry-leading team from Design Resource & Service, ensuring the most precise machine tool diagnostics and calibration available.

We also offer fast, practical ballbar testing to assess machine performance. A ballbar test either before or after calibration shows the resulting circularity of the axes, including identifying the components that affect circularity. A great diagnostic tool to ensure that your machine is performing as it should.
