OEM Optical Glass Sapphire Window

Sapphire cutters are used for high-quality and fine treatment of copper, alumi-num, and their alloys, as well as for nonmetallic materials. In comparison with their hard-alloy analogs, sapphire cutters provide better treatment accuracy and a higher class of surface finish at smooth feed. The sharpening angles of the cutting plate and the working conditions for one of the types of cutters are presented in Fig.  Sapphire microcutters are used in microinstrument making. 

Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
