RENISHAW SFM-G1 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 G-series of modules is designed for the measurement of small grooves and geometrical features. Feature depth, width, spacing etc. are reported instead of roughness parameter values.

Typical applications

Grooved engine bores prepared for PTWA coating.

Specification

Stylus tip radius (µm)	10
Typical groove feature measurement accuracy *	±10%
Feature depth range (mm)	0.02 – 0.3
Skid / stylus arrangement	Side-by-side
Skid material	DLC coated stainless steel
Nominal stylus tip protrusion beyond skid (mm)	0.5
Skid length / radius (mm)	4 / 40
Skid width / radius (mm)	2 / 12.5
Skid contact force (N)	0.2
Stylus contact force (N)	0.003
SFM / SFH knuckle adjustment range	±90°
Weight (g)	12
Resolution (nm)	1
Measurement speed (mm/s)	Up to 1
