[CAD_CAM_EDM_DRO] Probes

Hi All

Does anyone here have experience with commercial probes, like Renishaw?

I've been looking at some designs, and what concerns me is tip-changing.
I can't find any documentation to explain how a device that is sensitive to
0.2g touching can withstand the screwing off, and in of a different tip
without possibly distorting the internals.

Also, when a probe is mounted in the spindle, and although it usually does
not turn, is the ball at the end meant to be concentric with the mill
spindle to within the accuracy of the probe, like less than a 1um?
