Abstract

An abrasive disk is founded by ordinary casting process. The chemical composition of the casting (weight percentages)is : molybdenum 0.3%-0.6%, copper 0.7%-1.0%, carbon 2.8%-3.2%, manganese 0.9%-1.3%, phosphorus 0.15 %-0.4%, silicon 1.6%-2.0%, remainder is iron. Its abrasive resistance is excellent, useful life is long, and it could process over one million crystal films.

Description

1. Technical field [0001] The invention relates to a workpiece surface grinding tool, in particular to a grinding disc. 2. Background technology [0002] For the processing requirements of high flatness on the surface of the workpiece, the method of grinding is usually used. Grinding and polishing machines are used for plane grinding and polishing. Generally, a grinding disc is used. The grinding disc is divided into an upper grinding disc and a lower grinding disc. The material of the grinding disc is directly related to the service life of the grinding disc. And the material that existing grinding disc adopts is gray cast iron, and its wear resistance is poor, and service life is short, can only process 200,000 crystal chips. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art, and provide a kind of grinding disc, which has good wear resis...
