Product Description

Metal Machine Surface Roughness Instrument Tool

it is not as straightforward as most other engineering measurements such as length or angle or hardness' and in order to get good accuracy, expensive instruments are required. These are often unsuitable for workshop use, where the roughness of the machined surface can usually be assessed conveniently and with sufficient reliability using visual and tactile comparison with a standard set of surfaces machined in the same way.
This set contains standards for the six most important machine methods in the prevalent"AA" values, These surface roughness is used to compare and determine the degree of the surface finish by comparison method and eye estimation or magnifying glass,

 

Feature: 

1-  standardized in ISO2632/-1975
2-  made of 45 super carbon steel except for the GCr15 which is used to plat lapping the sample block.
3- All 30 specimens are calibrated in μ"AA"(arithmetic average) and in the metric equivalents um Ra.
