Scraping platform and the grinding platform is different on appearance, usefulness, precision, and processing technology.

The working surface of the scraping platform has knives and knives. But the grinding platform has been machined again, the surface is smooth, oily and sky blue, and there are no knives on the working surface.

Scraping platform DIN876/II

The grinding platform has higher precision than the scraping platform, the surface of the platform is ground and the flatness error is small.

The grinding platform is generally suitable for inspection and use in precision scientific research departments such as optics. The grinding plate has uniform organization, compact structure, no defects such as blisters, pores, looseness, easy sanding, uniform and rich sand distribution, strong sand embedded and strong cutting performance, smooth surface, oily, sky blue, and good wear resistance. The grinding platform is machined after manual scraping and grinding.

The scraping platform is mainly used for the grinding of parts and the repair of measuring tools. The accuracy is 0, 1, 2, and 3. In order to achieve the purpose of leveling the working surface.

How to choose grinding platform and scraping platform?

A grinding platform with good flatness and surface roughness should be selected. Usually, the gap between any two pieces of a set (3 pieces) of grinding platform is less than 1/2 of the grain size of the emery to be pressed. Therefore, before grinding, the flatness of each plate must be measured by the 0-level knife edge light gap method (white light flatness greater than or equal to 2.5μm, red light flatness 1μm-2μm, blue light flatness 0.5μm-1μm, opaque The flatness is less than or equal to 0.5μm.
