Cast Iron Inspection Plate
Cast Iron Inspection Plate can be made into rib type and box type and the working surface are typically square, rectangular or round and are allowed to machined V, T or U-shaped grooves and round holes or other holes.
Material:
The material of Cast Iron Testing Plate is high-strength cast iron HT200 and HT250. After two times’ artificial heat aging treatment( Artificial annealing temperature 600℃ to 700℃or 2-3 years natural aging) the internal stress was totally eliminated, so the surface plate have stable accuracy and good wear-resisting performance.
Usage:
Cast Iron Testing Surface Plate is always used as the datum for measurement of the machinery parts’ geometric tolerance,such as flatness, parallelism, straightness and more. It is also can be used for precision inspection, marking out (layout), and tooling setup. It is an indispensable basic equipment in most mechanical manufacturing industries.
