Scraping is the use of tools like scrapers, reference surfaces, measuring tools and display agents to Manual, scrap, grind and measure, so that the workpiece can reach the size, geometry, surface roughness and adhesion specified in the finishing process.

In addition to ordinary properties, cast iron floor bed plate also have unique characteristics: 1. Cast iron flat plate, with good machinability after light sand guide, and feel smooth when grinding.

The cast iron floor bed plate can be used to inspect the flatness of the parts by the coloring method, which has the advantages of accuracy, intuitiveness and convenience. Pushing the watch seat on the cast iron flat plate that has been scraped and the workpiece is smoother, without any astringency, and can be accurately measured.

The preparation work before sand pressing is very important. What kind of tablet should be chosen first? Which sand pressing method is used? What specifications of sand should be used?

The assembly platform is a workbench that is indispensable for marking, measuring, riveting, and tooling technology, and it can also be used as a channel for mechanical experiments and so on.

Cast iron box tables are mainly used to check the parallelism and perpendicularity of parts and support the workpiece when scribing. They are generally cubes or cuboids with the same side length.
