market analysis of China's superhard material tool industry

distribution date:

core tip: in the current tool market, the tool materials that occupy the largest market share are still high-speed steel and cemented carbide, However, the maximum hardness of these tools is only 2000 ~ 3000hv. If bonding materials are added, the overall hardness is below 2000hv. For difficult to machine materials and high-speed and high-precision machining, tool materials with low hardness are no longer competent. Superhard material tools represented by diamond and cubic boron nitride tools quickly occupied this market. In recent years, with the continuous development of workpiece materials, especially the emergence of some difficult to machine materials, superhard material tools have been more and more widely used, including diamond tools and cubic boron nitride tools. The number, scale and manufacturing level of domestic superhard material tool manufacturers are rapidly improving, and the new material industry as the leading industry of the national economy is high. In China, superhard materials and superhard cutting tools are mainly concentrated in Henan. The most representative is Henan funike Superhard Material Co., Ltd., which has always been a pioneer in the superhard material industry and has advanced superhard tool R & D and manufacturing technology

in the current tool market, the tool materials that occupy the largest market share are still high-speed steel and cemented carbide, but the highest hardness of these tools is only 2000 ~ 3000hv. If bonding materials are added, the overall hardness is below 2000hv. For difficult to machine materials and high-speed and high-precision machining, tool materials with low hardness are no longer competent. Superhard material tools represented by diamond and cubic boron nitride tools quickly occupied this market. Among them, the diamond knife has extremely high hardness and wear resistance, and its hardness can reach 10000hv. It is the hardest tool material, and its thermal stability can reach 700 ℃ ~ 800 ℃. The hardness of cubic boron nitride is second only to diamond (up to 8000hv ~ 9000hv), and its thermal stability is higher (up to 1250 ℃ ~ 1350 ℃)

superhard material tools have the characteristics of high processing efficiency, long service life and good processing quality. In the past, they were mainly used for finishing. In recent years, due to the improvement of the production process of artificial superhard tool materials, the control of raw material purity and grain size, the use of composite materials and hot pressing technology, the scope of application has been expanding. In addition to general finishing and semi finishing, they can also be used for rough machining, It is internationally recognized as one of the most promising tool materials to improve productivity. Using superhard materials to process steel, cast iron, non-ferrous metals and their alloys and other parts, the cutting speed can be one order of magnitude higher than that of cemented carbide, and the tool life can be dozens or even hundreds of times higher than that of cemented carbide. At the same time, its emergence also changes the traditional process concept. Turning and milling can often be used directly instead of grinding (or polishing) with superhard tools. For the processing of hardened parts, a single process can be used to replace multiple processes, greatly shortening the process flow

diamond cutting tools have extremely high hardness and wear resistance, and can effectively process non-ferrous metals such as copper, aluminum and their alloys, and natural materials | & nbsp; Biodegradable materials PHA ceramics, non sintered cemented carbide, various fiber and particle reinforced composites, etc. Diamond is commonly known as diamond, which is what we often call diamond. Natural diamond deposits have been formed in prehistory, and there is no growth law to follow. Synthetic diamond is mainly used in military industry and aerospace industry. Because it is resistant to high temperature and high pressure, it is needed for astronauts' helmet membranes, spacecraft heat shields, high-speed rail sleepers, etc. Professor Wang Qinsheng, chief engineer of Henan diamond and products engineering technology research center and the host of the project, said that artificial diamonds are also widely used in advanced manufacturing and modern processing industries, ranging from dental repair and inlay knives, bone grinding knives in cosmetic hospitals, to automotive bearings and electronic components. The large corrugated sheets inlaid with artificial diamond can be used to cut huge stones and highway cement. Generally, these standards have strict provisions on sample preparation and experimental methods, and also play an important role in qualitative exploration and oil exploitation
