Diamond tools has changed the traditional machining process, solve a lot of production and processing problems previously difficult to solve. Now widely used in machinery, metallurgy, mining, high-speed trains, cars, tractors, bearings, pumps, transportation, energy, precision instruments, aerospace and other industries Bing has made significant economic benefits. Machine using a diamond cutter must have a high rigidity, high power and high speed. In addition, better precision machine tools, jigs and clamping the workpiece clamping device, requiring high reliability, so as not to cause vibration when machining tool breakage. It must be noted, many of the current production machine equipment can not meet the processing requirements of diamond tools, so their potential has not been fully future, with the increase of CNC machine tools and machining centers, high-device applications, will further promote the diamond tool used. Diamond tool materials into single crystal diamond, artificial and synthetic polycrystalline diamond composite polycrystalline diamond and carbide blade and CVD diamond.      Diamond is the large-diameter, fine-grained, high impact resistance, thermal stability direction. At present, China's annual production of synthetic diamond largest in the world, and can produce a variety of high-grade synthetic diamond and high strength for the promotion and use of diamond cutting tools created favorable conditions. Diamond tool machining and grinding mill with a blunt heavy use is the key issue, it is a highly secret, very difficult technology. Foreign companies using diamond tools not own the majority of the Brothers, but will return with a blunt diamond tools factory resharpening. China's current development of diamond tools, one should pay attention to the introduction of foreign technology, to try to improve the quality of the blade, the blade to reduce costs; hand to further develop the finer grain material to increase its density, reducing blade mouth jagged edges, as it can be more sharp grinding, diamond tool to solve simultaneously the efficiency and the quality of grinding.
