Radio Touch Probe Brings ‘Out of Sight’ Precision
Bringing "out of sight" precision to complex 3D part measurement on machine tools, the Renishaw RMP600 touch probe combines two exclusive Renishaw technologies — highest accuracy strain-gage sensing and frequency-hopping spread-spectrum (FHSS) radio transmission. The industry-first design allows unmatched part checking precision on 5-axis machining, contours, deep cavities, undercuts, etc. where obstacles or part features can block transmission by optical line-of-sight probes. The versatile probe makes possible rapid, automated part set-up and changeover, in-process control of critical dimensions, and even final inspection on certain parts to speed throughput and reduce WIP. Robust construction, compact design, solid-state electronics and interference-free signal transmission allow application to all sizes of machining centers, the harshest of machine environments and "noisy" plant floors with competing wireless Wi-Fi communications.
Using Renishaw's patented RENGAGE technology combines a patented sensing mechanism and advanced electronics to allow sub-micron 3D probe performance on contoured surfaces, even with long styli. The probe delivers greater levels of accuracy than possible from a standard mechanical probe, giving uni-directional repeatability of 0.25 µm (0.000010 in) with a 50 mm long stylus and 0.35 µm with a 100 mm stylus. It is recommended for styli up to 200 mm.
