The main raw material manufacturing diamond blade carbide and high speed steel is an important auxiliary materials APT, is the production of major raw materials and intermediate products market transactions in the form of tungsten , tungsten is currently the main producing areas in the Alps, the Himalayas and the Pacific Rim areas. China has 60 % of the tungsten deposits , due to the shortage of raw materials , APT prices in recent years, nearly ten times the growth in the international market . The increased costs will eventually be passed on to end-user tool body . At present relevant research institutions in the world for such situations , the ongoing active research , major research program is the maximum extent possible to reduce the amount of tungsten in tool , the main method is used only in a critical part of tungsten tool . With the application of new materials, research new technologies , ceramics, cubic boron nitride , diamond these tools and materials have better prospects. For mechanical processing , reduce production costs is the most effective way of productivity . Cutting ( cutting speed , cutting the amount of time units ) increased by 20% , production costs will be reduced by 15%. Increasingly stringent processing requirements needed tool materials and coatings for further development, improving working conditions and improved tool design . In the process , there will at the cutting edge and sudden changes in temperature and mechanical force vigorous chemical reactions require the use of more excellent tool material and tool surface coating. In addition to the productivity needs , the more difficult materials in the field of machining applications, and to deal with these difficult to cut materials processing , the most effective way is the advent of advanced cutting tool materials , " Valin superhard " It is seen that, discarded other business -related industries in the field of superhard materials , "not large and only high-precision special" main CBN tools in multiple cutting difficult materials and high collar leading the field . Diamond blade industry's market broadly distributed in the general machinery and automotive fields. Global machine tool sales were the main customer base of general machinery and automotive industries , each accounting for about 35 percent , followed by aerospace, medical and mold industry , the distribution between clients from 10% to 5%. Growth in the global auto industry, the largest contribution to Asia , with China leading the absolute impressive 40 % growth over the same period the average global growth rate of less than 5 %.
