[PN: S-22M]

METRIC (MICRO-M) SURFACE ROUGHNESS & FINISH STANDARDS SET

METRIC (MM) SURFACE ROUGHNESS & FINISH STANDARDS SET

The S-22M, Metric Microfinish Surface Roughness Comparator provides industry with established flat surface roughness specimens for visual and tactual comparison.  It is used in specifying and controlling surface roughness when a product having the appearance of typically machined surfaces required. The Microfinish Comparator provides an economical tool which permits roughness to be specified on the same basis as linear measurements.  The surfaces presented are the result of years of research and engineering.

The Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements. The surfaces presented are the result of years of research and engineering. Surface Roughness Scale is made by a dual electroforming process wherein nickel is electrodeposited to provide an exact reproduction in intricate detail.

The surfaces used in this scale are reproductions of accurately turned surfaces measured in microinches (millionths of an milli-meter). The numbers engraved alongside each surface are the average deviation from the mean surface expressed in Micro-Meters.

 

Note: Picture shown is S-22 inch unit version... S-22M is identical, except units are metric.
