Scraped Surface Plate

Scraping involves scrape and lapping. After many times’ scraping ad lapping, the surface roughness and geometrical errors of the Scraped Surface Plate are reducing gradually and the contact accuracy and geometric accuracy of the Scraped Surface Plate are improved gradually until all the values reach to the requirements.

Usage:

Scraped 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.
