SFM surface finish modules

The SFM modules for the SFP2 probe system have been designed to suit the demands of specific parts and features encountered in a precision manufacturing environment.

Each SFM module is its own miniature measuring device, incorporating Renishaw's proprietary encoder system to transduce the motion of the stylus tip.
