Grinding wheel and polishing process using same

Abstract

The invention discloses a grinding wheel and a polishing process thereof. The grinding wheel comprises phenolic resin, a monomer for generating a polyurethane elastic material, silicon salt, white carbon black and a grinding material, wherein the dosage of the phenolic resin is 6-13 parts by weight, the dosage of the monomer for generating the polyurethane elastic material is 12-30 parts by weight, the dosage of the silicon salt is 3-10 parts by weight, the dosage of the white carbon black is 1-4 parts by weight, and the dosage of the grinding material is 50-70 parts by weight; the phenolic resin, the silicon salt and the grinding material are mixed, and then wetted with water, so as to facilitate acid-base neutralization reaction and generate a gel; after the monomer for generating the polyurethane elastic material, and the white carbon black are uniformly mixed, the gel is immediately added, the materials are uniformly stirred, and the uniformly-stirred materials are injected in a mould and moulded to obtain the grinding wheel. Compared with the prior art, the grinding wheel disclosed by the invention has a function of smoothly grinding the surfaces of workpieces, and further has the advantage of a mirror polishing function.

Description

Technical field: [0001] The invention relates to a polishing technology. Background technique: [0002] In the existing mirror polishing, the polishing wheel used is determined by its structural characteristics. There are mainly two types, one is grinding, and the other is mirror polishing. Restricted by the performance of the polishing wheel itself, the grinding polishing wheel It can only grind the surface of the workpiece, but can not achieve the effect of the mirror surface, and the polishing wheel for mirror polishing can only achieve the effect of mirror polishing, but cannot achieve the effect of smoothing the surface of the workpiece. Therefore, the existing mirror polishing process It is composed of two processes of grinding and polishing. Since a large amount of coolant needs to be injected during the polishing process, it is time-consuming and laborious, and the polishing cost is high. Moreover, the polishing process is complicated and the process is long. A large...

Therefore, the existing mirror polishing process It is composed of two processes of grinding and polishing. Since a large amount of coolant needs to be injected during the polishing process, it is time-consuming and labor-intensive, and the polishing cost is high. Moreover, the polishing process is complicated and the process is long. A large amount of polluted wastewater
