 Abrasives are used for grinding, grinding and polishing tools. Most of the abrasive is made of abrasive man-made binder with abrasive, but also useful for processing of natural ore directly into the natural abrasive. In addition to grinding and other metalworking machinery manufacturing industry has been widely used, but also for food processing, paper and ceramics, glass, stone, plastic, rubber, wood and other non-metallic materials processing. Abrasive in use, when the abrasive blunt, because the grain itself part of the fracture fragments, or combination of agents, abrasive from the abrasive on the partial or complete loss, while the abrasive surface of the abrasive work of emerging new cutting edge, or continuously exposing new sharp abrasive, so abrasive in a certain period of time to maintain the cutting performance. This self-sharpening abrasive, is abrasive, compared with the general prominent feature of the tool. 
 As early as the Neolithic Age, human beings have begun the use of natural millstone processing knives, axes, bone, horn, etc. devices, and dental tool; in 1872, appeared in the U.S. using a combination of natural abrasive and clay firing ceramic wheel; 1900, the advent of artificial abrasives, synthetic abrasives manufactured using a variety of abrasives have been produced for grinding and grinding machines to create the conditions for rapid development. Since then, the natural abrasive in abrasive proportion gradually decreased. Their source of abrasive material, a natural abrasive and abrasive man-made categories. Commonly used in machinery industry is only natural abrasives Whetstone. By the basic shape and abrasive man-made structure The distinction between grinding wheel, grinding head, Whetstone, sand tile (collectively bonded abrasives), and five types of coated abrasives. In addition, the abrasive is also used as a class of abrasives. 
 Bonded Abrasives Abrasive mainly by the diamond, cubic boron nitride and other solid form with the combination of the abrasive agent. As diamond, cubic boron nitride high price, with good wear resistance, abrasive products made with them with different abrasive abrasive materials, in addition to super-hard abrasive layer, there are transition layer and matrix. Abrasive cutting action layer is the part played by the super-hard abrasive and bond composition. Matrix is ??supporting for the grinding role played by the metal, bakelite, or ceramic material composition. Transition layer for connecting the substrate and superhard abrasive layer, constituted by the binder, and sometimes can be avoided. Are commonly used binder resin, metal, plating metal and ceramics. 
 Bonded Abrasives manufacturing processes are: distribution of materials, mixing, forming, heat treatment, processing and inspection. With the combination of agents is different manufacturing processes are not the same. Vitrified bond mainly-pressure method, the abrasive and bonding agent ratio by weight of formula, after weighing, mixing machine placed evenly mixed into the metal mold, forming the abrasive in the press on the blank. Rough kiln dried and then into the roasting, sintering temperature is generally about 1300 ℃. When using low melting point Shaorong binder, the sintering temperature below 1000 ℃. Precise shape of the required size and then processing, final inspection products. 
 Resin bonded abrasives are generally at room temperature in the press molding, there is also heated in the heating side of pressure below the hot pressing process. Hardening furnace hardened after forming. With phenolic resin binder, the curing temperature of 180 ~ 200 ℃. Rubber bonded abrasives roll machine mainly used for mixing, and rolled into thin slices, then use the knife punching molding; also some with loose material, press on the inner metal mold into shape. Curing in the curing tank after forming, the temperature is 165 ~ 180 ℃. 
 Particular variety of abrasive and grinding with sintered fiber abrasive such as corundum. Sintered alumina abrasive is alumina and the amount of chromium oxide mixture, molding, sintering is made at about 1800 ℃. The abrasive compact, has high strength, mainly used for processing clocks, instruments and other parts. Fiber abrasive or adhesive is used with a abrasive filaments (eg, nylon) as raw material, its flexibility, and is mainly used for polishing metal materials and products.
