Product details
Inspection cast iron flat plate
Use: Suitable for various inspection work, the reference plane for precision measurement is used for machine tool mechanical inspection and measurement reference to check the dimensional accuracy or shape deviation of parts, and Making tight lines is also an indispensable basic tool in mechanical manufacturing.
Inspection of plate accuracy: It is carried out in accordance with the national standard metrological verification procedures, which are divided into three levels and five levels.
The inspection plate
should be made of high-quality, fine-grained gray cast iron or alloy cast iron, and its working surface hardness should be ~B.
The scraping process should usually be used to inspect the flat working surface. For the grade 3 flat working surface processed by scraping, the maximum allowable value of surface roughness R is.
