Surface roughness stand comparator
1. As standardized in ISO2632 / I-1975
2. This set contains standard for the six most important machine
methods in the prevalent AA values.
3. These surface roughness is used to compare and determine the
degree of the surface finish by comparision method and eye
estmation or magnifying glass.
4. The surface rough contrast blocks is made of 45 super carbor
steel except the GCr 15 which is using to plat lapping the sample
block.
5. All 30 speciments are calibrated in u AA (Arithmetical Average)
and in the metric equivalents um Ra.

Notice of Operation and mainteneceWhen working the surface rough contrast block should be as posible
as under the same condition with the checked workpiece (including
surfacecolour.illuminating condition etc) and it is forbidden to
contact the surface rough contrast block direct by hand.Antitrust
treatment should be strictly followed to avoid corrosin and strike
and scrape should be avoided.
