China has been working hard in the field of super-hard materials for half a century. The use of super-hard materials and super-hard materials has obtained a large amount of cubic boron nitride, which has been applied in many high-tech technologies. In the satellite, we used cubic boron nitride. At the time, we were still in the embryonic stage in the research of cubic boron nitride. The improvement of innovation ability and technology level, product quality upgrading and structural adjustment have made great achievements that have attracted worldwide attention, changed the pattern of the world cubic boron nitride industry, and laid a solid foundation for catching up with the world's advanced level, so that we have realized The dawn of a superhard material powerhouse! China's superhard materials industry has undergone 38 years of development. Although China has become a major producer of superhard materials in 2000, the development of superhard products lags far behind the development of materials, which also provides sufficient development for superhard products. Source of raw materials. With the extensive use of diamond, CBN and its products, the development of super-hard materials and products has formed a new industry. It can be said that the application of super-hard materials has promoted the development of the CBN industry.
Recalling that from 1957, RH Wintov of the United States first developed the Boron Nitride. In 1967, China successfully developed the first cubic boron nitride. In the next 20 years, China is still in a stagnant state in the research of cubic boron nitride industry. Until 1985, the founder of Fenike began to study CBN abrasives. In 1988, Fenike successfully developed the first synthetic high-grade cubic boron nitride abrasive. This technology has injected new blood into the development of China's CBN industry. This makes Fu Nike occupy an important position in the research technology of cubic boron nitride abrasives in China and the world.

From the 1990s to the beginning of this century, China's CBN industry has developed rapidly (Figure 1), forming a complete range of CBN single crystal product systems that can meet different application requirements. The global total output should be 5 About 100 million carats, China is still a big producer, with a production volume of about 55% to 60%. Of course, during this period, Fenike continued to contribute to the development of China's CBN industry. In 1991, Fenike developed amber cubic boron nitride. In 1996, Fenike established the company and became the largest mass production in China. Grade Cubic Boron Nitride Abrasive R&D and Manufacturing Center; In 1997, Fenike developed high-strength black cubic boron nitride successfully. In 2002, Fenike's technical researchers drafted the Chinese cubic boron nitride standard. Up to now, Fenike has always made unremitting efforts to make an indelible contribution to the development of China's CBN industry in the CBN industry.
