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.
Few manufacturing companies rely on ballbar testing to maintain machine tool accuracy as thoroughly as Silfex. Now, advanced training and a move to a Renishaw QC20-W wireless system have enabled the company to take the benefits of ballbar testing to a higher level.
While countersunk and chamfered holes are similar in appearance, functionally they are quite different. Consequently, different gages exist to serve these different functional requirements.
The uses of working gage blocks are as varied as the number of gage blocks in a large set. The working blocks have an intermediate grade and are often used in the inspection or calibration lab, but they may also be found on the shop floor.
