- The kit included 30 roughness of the 6 most important machining processes:
Flat Lapping, Surface Grinding, Reaming, Horizontal Milling, End Milling, Cylindrical Turning
- the individual wear-resistant, stainless reference standards are 22 x 10 mm

- weight 0,12 kg
- inclusive instruction manual
- delivery in protective cover
The Microsurf scale consists of a number of specimens of surface machined by a particular type of
process identified on the top label, whilst the roughness values of each patch are given on the middle
label in terms of the parameters Ra and Rz-DIN, together with N-classes, in both microinches and
micrometers. The actual values of the patches are within the tolerances allowed by the standards
BS 2634, ISO 2632, and ANSI B 46.1. The parameters and procedures for measuring them are defined
in BS 1134 and BS ISO 4287. Please note that the terms "CLA" and "AA" mean exactly the same thing as "Ra".
