Additional information

Enhanced access and inspection capability for integrated surface finish measurement

SFM-E2Features

The E-series of modules use a two-part skid 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.

Typical applications

Automatic transmission valve bodies, minimum feature access (mm): 9 122 (max. depth).

NOTES:

Not compatible with SFH-2.

Scan speeds may need to be reduced for finer finishes.
