Suitable materials for improving accuracy by scraping and grinding processes are

The material suitable for improving accuracy by scraping technology is metal. Scraping is one of the methods of plane finishing. Its purpose is to reduce the surface roughness value, improve the contact accuracy and geometric accuracy, so as to improve the matching stiffness, lubrication performance, mechanical benefit and service life of the machine tool. It is also a necessary processing technology for machine tools and cast iron plates, which is difficult to achieve only with surface grinder and guideway grinder.
