Surface reference samples TOP-VERSION !!
the wide range is compared: Ra values from 0,05 to 12,5 μm (microns)
the wide range is compared: Rz values from 0,55 to 50 μm (microns)
also N-normalized values and Rz values are listed
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
external dimensions 150 x 75 x 5 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
n BS 1134 and BS ISO 4287. Please note that the terms "CLA"
and "AA" mean exactly the same thing as "Ra".
