Application of Polycrystalline Diamond Composite Sheet
In the past ten years, my country and some industrially developed countries have paid special attention to the production and application of diamond polycrystalline composite sheets. And competing to develop and produce, with many varieties and specifications, and gradually popularized and applied at home and abroad, all because of its excellent performance:
Starting with the synthesis of cubic boron nitride (CBN) by RH Wentorf of GE in the United States in 1957 using ultra-high pressure technology, CBN was also successfully synthesized in the former Soviet Union, Germany, Japan and the United Kingdom in the 1960s and early 1970s. Zhengzhou Institute of Abrasive Grinding synthesized the first CBN in China in 1966, which opened the prelude to China's CBN research and industrial production.
Diamond and CBN metal bond abrasives formulation design
Synthetic diamond and CBN have high hardness and wear resistance, and are currently the hardest substances in nature. As a superhard material, it is widely used in various products, including abrasive products: such as grinding wheels, grinding stones, rollers, etc.; cutting tools: saw blades and saw blades for various stone materials; geological drilling: geological drill bits, hole protection Devices; tools: such as turning tools, milling cutters, boring tools, reamers, files, drawing dies, etc.
