Title:
LARGE-SIZE SINGLE CRYSTAL DIAMOND GRINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/078247
Kind Code:
A1
Abstract:
Provided is large-size single crystal diamond grinding method, in which a carbide is generated by chemical reaction of carbon atoms and active abrasives of the large-size single crystal diamond under specific grinding conditions, and then the generated carbide is removed by using hard abrasives, to obtain high-efficiency and high-quality ground diamond surface. The grinding fluid is deionized water, has no pollution to the environment, and has a grinding speed much lower than that of dynamic friction processing. Different from the conventional diamond graphitization removal method, the grinding method can obtain the diamond surface with lower surface roughness, fewer cracks and shallower grooves, which can reduce the processing cost.
