What is the role of the double-sided grinding machine when oxidizing during operation?

Source of information: http://seocai.com Time: 2018/11/16 10:19:43

In the air, the phenomenon of oxidation will promote the grinding to a certain extent, because the air will affect the temperature drop during grinding, and the oxidation in the air will quickly oxidize the surface of the workpiece, forming the surface of the workpiece An oxide film.

In the process of double-sided grinding , the existence of an oxide film on the surface of the workpiece will reduce the possibility of adhesion of the abrasive particles. For some abrasive materials, the surface will be oxidized under high temperature conditions, which will gradually be consumed.

Abrasives will be thermally unstable and oxidized at a certain temperature.

1. Silicon carbide will oxidize at a certain temperature during the process, and when the friction surface is damaged, the new surface will be oxidized.

2. Due to the completeness of crystal development and the difference of trace elements contained in diamond, the strength and thermal stability of diamond will also be different. Surface oxidation and graphitization will occur in the air.

3. Cubic boron carbide with super-hard abrasives is second in hardness to diamond. Due to their better mechanical wear performance, chemical wear is relatively important. Under high temperature conditions, the surface of the grains will form an oxidation phenomenon and become glass The temperature of the abrasive of boron oxide is much lower than that of ordinary abrasives, which can effectively reduce the degree of oxidative wear.
