RENISHAW SFM-C3 Surface Finish Probe Module
Surface finish probe module
Enhanced access and inspection capability for integrated surface finish
measurement
The SFP2 system consists of a probe and a range of SFM modules which have been
designed to suit the demands of specific parts and features encountered in a
precision manufacturing environment. The probe and modules can be
automatically interchanged with all other REVO® probe options, providing the
flexibility to easily select the optimum tool to inspect a wide range of
features.
Each SFM module is its own miniature measuring device, incorporating
Renishaw’s proprietary encoder system to transduce the motion of the stylus
tip.
Features
The C-series of modules have the ability to locate the stylus in small
diameter bores. The skid and stylus are inline so that both travel along the
axis of the bore.
The SFM-C3 is a replacement for SFM-C2, offering more stylus range and
increased robustness without any degradation in performance.
Typical applications
Automotive engine valve guideways.
