SFM-A2 Surface Finish Probe Module
Installation Guide
SFM-A2 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 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 A-series of modules is designed to deliver high performance with a good level of capability to access part features. The cranked skid arm design of the A2 module provides additional clearance around part features.
Typical applications
General purpose; engine block gasket face, lateral scanning of crankshaft bearing journals.
