The development of superhard materials in China and their application in hardware machining have demonstrated the performance characteristics and scope of application of synthetic diamond and cubic boron nitride, further strengthening the research, development, and promotion of superhard material products.

Artificial diamond and cubic boron nitride are collectively referred to as superhard materials, among which diamond is a hard material with various properties such as high thermal conductivity, high insulation, high chemical stability, and high-temperature semiconductor characteristics. It can be used for processing non-ferrous metals such as aluminum and copper. Cubic boron nitride is a superhard material with high hardness, high thermal stability, and high chemical stability, second only to diamond in hardness. In addition, diamond and cubic boron nitride have good infrared transmittance and a wide bandgap, which are widely used in cutting-edge industrial fields such as electronics and aerospace.

Diamond abrasives and their products are mainly used for processing various difficult to machine materials of non-ferrous metals such as stone, glass, cement products, refractory materials, etc. Diamond grinding wheels can be used for various hard alloy cutting tools that are widely used in Beijing Machinery Processing Factory. Especially for some complex and high-precision cutting tools, using diamond grinding wheels for processing can better demonstrate their performance.
