Renishaw PH20 5-axis touch-trigger probe

The new PH20 head, to be launched at MACH 2010, incorporates two rotary axes and draws on the REVO 5-axis scanning probe head technology, which was launched at MACH 2006. Whereas REVO offered full contact scanning, the PH20 probe head offers unique 'head touches' for rapid touch-trigger measurement.

So, for example, it can measure holes/bores simply by employing the two rotary axes in the head, with the CMM frame remaining static. The result is improved accuracy, repeatability, and significantly improved inspection throughput, with parts measured up to three times faster than current touch-trigger systems, it is claimed.
