Abrasives are tools used for grinding, grinding and polishing

Abrasives are tools used for grinding, grinding and polishing. Most of the abrasive tools are artificial abrasives made of abrasive plus binder, and natural abrasives directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, T41 green cutting disc size are also used in the processing of food processing, paper industry and non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood.
During the use of the abrasive tool, when the abrasive grains are blunt, the abrasive particles are partially or completely detached from the abrasive tool due to partial fragmentation of the abrasive particles or the binder breaks, and the abrasives on the working surface of the abrasive tool are constantly emerging. The cutting edge, or constantly revealing new sharp abrasive particles, allows the grinding tool to maintain cutting performance for a certain period of time. This self-sharpness of the abrasive tool is a prominent feature of the abrasive tool compared with the general tool.
As early as the Neolithic Age, humans began to use natural grinding stones to process tools such as stone knives, stone axes, bones, horns and teeth. In 1872, in the United States, natural abrasives and clay were combined. Ceramic grinding wheel; around 1900, artificial abrasives were introduced, and various abrasive tools made of artificial abrasives were successively produced, which created conditions for the rapid development of grinding and grinding machines. Since then, the proportion of natural abrasives in abrasive tools has gradually decreased.
Abrasives are classified according to their raw materials, including natural abrasives and artificial abrasives. Natural abrasives commonly used in the machinery industry are only oilstone. Artificial abrasives are distinguished according to their basic shapes and structural features. There are five types of grinding wheels, grinding heads, oilstones, sand tiles (collectively referred to as consolidated abrasives) and coated abrasives. In addition, it is customary to classify abrasives as a type of abrasive.
