SFM-E2
Surface finish probe module
Typical applications
Automatic transmission valve bodies,
minimum feature access (mm):
Ø9 × 122 (max. depth).
Enhanced access and inspection capability for integrated surface finish
measurement
The SFP2 system consists of a probe and a range of SFM modules that 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 E-series of modules use dual skids with a central stylus. This makes them
ideal for short scans on small to medium-sized bores which may be deep within
the workpiece.
Due to the extreme length of this module, Renishaw recommends that the CMM’s
capability to use the SFM-E2 should be verified before full implementation.
NOTES: Not compatible with SFH-2.
Scan speeds may need to be reduced for finer finishes.
