The angle grinder is used for grinding, lapping and polishing tools. Most of the tools are made of artificial abrasives abrasive and bond, also natural ore processing directly into natural abrasives. Abrasive in machinery manufacture and other metal is widely used in the processing industry, is also used in paper industry and food processing, ceramics, glass, stone, plastic, rubber, wood and other non-metallic materials processing.
Tools used in the process, when the abrasive wear,, due to the partial disintegration or abrasive bond breaks, partially or completely detached on the abrasive from the abrasive, abrasives abrasive constantly appear on the face of the new cutting edge, or continue to reveal new sharp abrasive, abrasive in a certain period to maintain cutting performance.
Abrasives-according to its sources of raw materials, and artificial abrasives natural abrasives for two classes. Common natural abrasive only stone in the machinery industry. Artificial abrasive according to the basic shape and structure of differentiated, grinding wheel, grinding, stone, sand w (more collectively bonded abrasives) and five categories of coated abrasives.
Bonded by common Abrasives bonded abrasives are conventional abrasive materials consolidated into a certain shape, and has a certain intensity of abrasive. Generally abrasive, Binder and stomatal structure, the three elements of this three part commonly known as abrasive.
Angle grinding abrasive according to the different abrasive, can be divided into ordinary Abrasives bonded abrasives and abrasive bonded abrasives. The former conventional abrasive materials such as corundum and silicon carbide, the latter made of diamond and cubic Boron Nitride abrasive.
Abrasive in grinding cutting action. Bonded abrasives consolidated into abrasive material is loose, there are two types of inorganic and organic. Inorganic binders are magnesite and sodium silicate, ceramic, organic resins, rubber and shellac. One of the most commonly used are ceramic, resin and rubber-bonded.
