Silicon nitride ceramic cutter (quanxu)

The metal cutting industry is a very important sector in the national economy, and it is inseparable from all walks of life. According to the statistics of 1988, the cost of cutting and processing in the United States is as high as 100 billion US dollars per year, of which the cost of cutting tools is 1 billion US dollars. With the development of the new technology revolution, it is required to continuously improve the cutting processing productivity and reduce the production cost, especially the development of CNC machine tools, and require the development of new tools that have higher cutting speed and wear resistance than cemented carbide tools. At present, various new materials that are difficult to cut with high strength, high hardness, corrosion resistance, wear resistance and high temperature resistance are increasing. According to the literature, this kind of material has accounted for more than 40% of the total number of workpieces processed internationally. Carbide tools are difficult to handle many of the new materials. On the other hand, the international production of cemented carbide has reached 1500.
