Precision with passion

We adjusted the tilt accuracy of the headstock with a compensation map in 10° increments. Usually only the 0°, 90° and -90° positions are adjusted. Renishaw XR20-W rotary axes calibrator provides rotary axes calibration with arcsec accuracy and user selectable steps.

Our customer needed to find out why the radial deviation of a 6m long piston rod was out of tolerance. We measured both horizontal and vertical straightness simultaneously with an XK10 geometric laser. To everyone’s surprise, the cause was in the horizontal deflection of the bed. The same instrument helped in the alignment.

Our customer relocated their big gantry type milling machine. We have provided a comprehensive check of key geometry figures, including machine bed twist. Finally, laser performance calibration for all linear axes was performed, including compensation, using our XL80 laser system.

By regularly checking key geometry positions and deviation trends, the customer is able to maintain high levels of quality in their small batch production over the long term. We use QC20-W Ballbar equipment and Microplan precision ceramic artefacts for our measurements.
