Additional information

Enhanced access and inspection capability for integrated surface finish measurement

SFM-C2Features

The C-series of modules have the ability to locate the stylus in small diameter bores without significant degradation in performance. The skid and stylus are inline so that both travel along the axis of the bore.

Typical applications

Automotive engine valve guide ways.

NOTE: Not compatible with SFH-2.
