Recently, the 20/30 coarse-grain high-grade synthetic diamond project technology and the 30/60 coarse-grain high-grade cubic boron nitride innovation fund project technology undertaken by Henan Zhongnan Industrial Company of China Ordnance Industry Group successfully passed the scientific and technological achievements hosted by Henan Science and Technology Department. Identification. The expert panel believes that the two technologies have broken the long-term monopoly of the technology abroad and filled the gap in the domestic production of high-grade diamond and cubic boron nitride products.
It is reported that the 20/30 coarse-grain high-grade synthetic diamond products produced by this technology have been tested by the National Abrasives Quality Supervision and Inspection Center. The technical indicators are far superior to the requirements of JB/T7989-1997, and the products not only replace imported products. It also has a strong impact on the international market with its significant price/performance advantage. The 30/60 high-grade coarse-grained cubic boron nitride product has been proved by users to prove that the tools have reached the advanced level of foreign tools and can completely replace imported products. The successful development of these two technologies marks that China's high-grade diamond manufacturing technology has reached the world level, and it also marks that China has entered the ranks of the world's diamond manufacturing powers from the world's diamond manufacturing countries.
