grinding and polishing tools

Most of the abrasive is made of abrasive plus artificial abrasive binding agent, is also useful natural mineral rock directly processed into natural abrasive. In addition to grinding and other metal processing machinery  abrasive manufacture manufacturing industry has been widely used, but also for food processing, paper industry and the ceramics, glass, stone, plastic, rubber, wood and other non-metal materials processing.
Abrasive in use, when the blunt abrasive, because cutting wheel  the abrasive agent or a combination of its own to break fracture, the abrasive grain  from the partial or complete loss, the working surface of the abrasive grinding emerging new cutting edge, sharp or continuously exposing new abrasive grains, the abrasive can be maintained within a certain time cutting. This self-sharpening abrasive is abrasive tool compared with the general prominent feature.
Abrasives source of their raw materials, with natural and artificial abrasive abrasive categories. Commonly used in machinery industry is only natural abrasive Whetstone. Artificial abrasive characteristics according to the basic shape and structure of the distinction between a grinding wheel, grinding, stone, sand tile (the foregoing collectively referred abrasive) and coated abrasives five. In addition, it is customary also put abrasives abrasive as a class.
Bonded Abrasives are used by different abrasives can be  stone cutting wheeldivided into ordinary abrasive abrasive and superabrasive abrasive. The former corundum and silicon carbide and other common abrasive, the latter with diamond and cubic boron nitride and other superhard abrasive material. In addition, there are some special varieties, such as sintered corundum abrasive and so on.
By ordinary abrasive abrasive abrasive solid binding agent to form a certain shape common, and has a certain strength abrasive. Generally abrasive, binder and pore structure, these three parts are frequently referred to as the three elements of abrasive.
Abrasive abrasive cutting action play. Binding agent is a solid form of the abrasive loose abrasive materials, with inorganic and organic types. Inorganic binder with ceramic, magnesite, sodium silicate and the like; organic a resin, rubber and shellac. One of the most commonly used is a ceramic, resin and rubber binding agent.
