Radio Touch Probe--Renishaw

The Renishaw RMP600 touch probe combines the highest accuracy strain-gage sensing and frequency-hopping spread-spectrum radio transmission. The design allows part checking precision on five-axis machining, contours, deep cavities, undercuts, and more where obstacles or part features can block transmission by optical line-of-sight probes.

The Renishaw RMP600 touch probe combines the highest accuracy strain-gage sensing and frequency-hopping spread-spectrum radio transmission. The design allows part checking precision on five-axis machining, contours, deep cavities, undercuts, and more where obstacles or part features can block transmission by optical line-of-sight probes. The probe makes possible rapid, automated part setup and change-over, in-process control of critical dimensions, and even final inspection on certain parts to speed throughput and reduce work-in-process.

Using the company's Rengage strain gage technology, the touch probe is able to achieve far greater levels of accuracy than possible from a standard mechanical probe, making it ideal for a range of applications which demand high precision measurement, according to the company. The strain gage combines a sensing mechanism and advanced electronics to allow sub-micron 3D probe performance on contoured surfaces, even with long styli. The probe delivers uni-directional repeatability of 0.25 micrometers with a 50-mm-long-stylus, 0.35 micrometer with a 100-mm stylus and is recommended for styli up to 200 mm.  

The use of strain gages also allows the touch probe to trigger at much lower and consistent contact forces, resulting in less bending of the stylus and negligible pre-travel. Compatible with a range of machine controllers, the touch probe can be used with high-speed, single-touch or double touch probing routines.
