The difference between scraping and grinding platforms

1. Differences in appearance:

The working surface of the scraping and grinding platform has knife marks and patterns. The grinding platform has undergone another round of machine grinding, so the surface is smooth, shiny, and sky blue in color. There are no knife patterns on the working surface.

2. Differences in accuracy:

Grinding platforms are generally suitable for inspection and use in optical and other departments. Grinding plates have uniform organization, dense structure, no defects such as sand holes, pores, and looseness. They are easy to sand, with evenly distributed and abundant sand particles. The sand particles are firmly embedded and cut, with a smooth surface, shiny oil, and a sky blue color. The grinding platform is manually scraped and ground before being machine ground.
