Study on high-speed grinding of glass-ceramics

The quality of surface machining of glass-ceramic materials determines the performance of optical components. Low surface roughness and surface/subsurface damage in precision grinding is one of the machining conditions for the ultra-smooth surface of glass-ceramic materials. In this paper, the bowl-shaped diamond grinding wheels with different particle size and binding agent were used. First of all, the orthogonal tests of machining parameters such as different feed rates, spindle speed, and grinding depth at high speeds were designed. Secondly, the surface machining quality and stress distribution after grinding was analyzed. At last, the reasonable machining parameters for high-speed grinding of glass-ceramic materials were explored, in order to provide reference and basis for actual machining.
