Multi-Axis Calibrator Captures Angular, Linear, Straightness Errors

Renishaw’s XM-60 multi-axis calibrator can measure six degrees of freedom from a single setup and in any orientation for linear axes. The calibrator offers significant improvement in simplicity and time saving over conventional laser measurement techniques, the company says.

The XM-60 has been designed to measure machine errors directly, reducing the inaccuracies that can result from complex mathematics used in some alternative measurement techniques. It is capable of capturing angular, linear and straightness errors in a single setup. Direct measurement makes comparison before and after machine adjustments a quick and simple task with existing part programs for XL-80 measurement, the company says. The system uses the XC-80 environmental compensator to correct for environmental conditions.

The multi-axis calibrator provides a highly accurate laser system that incorporates an optical roll measurement and fiber optic launch system. The compact launch unit is remote from the laser unit, reducing heat effects at the point of measurement. It can be mounted directly to the machine on its side, upside down and even on its back, which is particularly beneficial in areas with difficult machine access. The receiver is fully wireless and powered by rechargeable batteries, eliminating trailing cables during machine moves that could cause inaccuracies or break the laser beam during measurement.
