What is the usage of arc abrasives？

     Arc abrasives are tool for grinding and polishing. Most of the arc abrasives are made of abrasive with the artificial abrasives, and also useful for the natural ore directly processed into a natural abrasive. In addition to mechanical manufacturing and other metal processing industry is widely used, but also for food processing, paper industry and ceramics, glass, stone, plastic, rubber, wood and other non-metallic materials processing.

     Arc abrasives in the use of the process, when the abrasive wear blunt, due to the abrasive grain itself part of the fracture or bond breaking, grinding grain from the abrasive or completely off, and the abrasive on the working surface of the new cutting edge, or continue to expose new sharp abrasive, so that the grinding tool in a fixed time to maintain the cutting performance. The self sharpening of the arc abrasive tool is a prominent feature of the tool.

     Early in the Neolithic age, humans have begun to use natural stone processing stone knives, axes, bone, horn and dental tools;In nineteenth Century the United States appeared in the ceramic grinding wheel which  is made of natural abrasives and clay.Around 1900,the advent of artificial abrasives.The use of artificial abrasives to produce a variety of tools have been produced, for the rapid development of the grinding and grinding machine to create the conditions.Since then, the proportion of natural abrasives in the abrasive gradually reduced.

     According to the source of its raw materials, there are two types:arc abrasive and arc artificial abrasives. In the machinery industry commonly used only natural abrasives whetstone. Artificial abrasives according to the basic shape and structural characteristics of the distinction, a grinding wheel, grinding wheel, oilstone, sand tile above collectively bonded abrasives and coated abrasives five categories. In addition, it is also used in the grinding agent as a type of arc abrasive.

     The hardness of the arc abrasive tool has a corresponding relationship with its dynamic elastic modulus, which is helpful for determining the dynamic elastic modulus of the abrasive tool by the audio method. In the grinding process, if the material of the workpiece material hardness is high, the general selection is low hardness of the abrasive; conversely, the selection is high hardness abrasive.
