The superhard tool is mainly made of diamond and cubic boron nitride. The tool is dominated by synthetic diamond composite (PCD) and cubic boron nitride composite (PCBN).
Many cutting concepts, such as green processing, to car grinding, milling and grinding, hard processing, high-speed cutting, dry cutting, etc. are due to the application of super-hard tool, so super-hard tool has become a cutting machine can not Lack of important means. With the progress of science and technology, the rapid development of manufacturing industry, the rapid development of CNC machining technology and the widespread use of CNC machine tools, superhard cutting tool production and application are more and more widely.
PCD and PCBN tools have been widely used in the fields of machinery, metallurgy, geology, petroleum, coal, stone, construction and other traditional fields, electronic information, aerospace, defense and other high-tech fields and automotive, home appliances and other emerging industries. Which has greatly promoted the rapid development of cutting and advanced manufacturing technology. The market has also expanded rapidly. It is reported that China's current PCD and PCBNCBN cutting tools have an annual output of 400,000 and sales of less than 200 million yuan. The authoritative department's survey shows that, The total potential sales of two kinds of tools will exceed 1.5 billion US dollars, it can be said that the super-hard tool industry promising. Despite this, but for China's super-hard tool, in order to catch this high-speed development of the ride, there are a lot of work to do, because the super-hard tool for high-end products, manufacturing strength, high technical threshold, the main For the control of foreign manufacturers, China only a small share, according to a domestic consulting site based on the super-hard tool industry manufacturers, downstream users visited the survey found that in 2009, the composite super-hard tool materials market global share of the former (20%), Sumitomo (18%), South Korea (9%), MegaDiamond (4.5%), TomeiDiamond (4.5%), and other companies are all foreign companies, %), Dennistools (4%), several major companies accounted for 90% of the market.
It can be said that China's super-hard tool is almost in the initial stage, and there are some problems that restrict the rapid expansion of the tool business, mainly in the following points. 1. Domestic PCD, PCBN material tool material uniformity is poor, the tool quality is not stable. 2. Domestic superhard tool grinding equipment manufacturing technology behind, still can not provide comparable with foreign companies tool grinding machine. 3. China's super-hard tool has not yet formed a standardized, serialized, leading to poor product quality consistency. 4. Super hard tool application basic research is not enough depth, not enough system, can not correctly guide the downstream business correctly and rational application. 5. China's super-hard tool also exists with the machine connection clamping method, blade clamping mechanism, tool material and structure, high-speed spindle tool clamping measures, rotary tool dynamic balance and a series of problems. 6. High-precision complex structure of the design and manufacture of super-hard tool, but for customs, such as for processing automotive, aerospace key parts of the super-hard tool Chinese enterprises can not manufacture.
