Introduction: grinding wheel is an important part of abrasive industry. Abrasive industry plays an increasingly important role in machinery production. Grinding wheel plays an indispensable role. With the development of science and technology, there are more and more new materials, and the processing is developing in the direction of high quality, high precision, high efficiency and automation. The application scope of ceramic bonded diamond grinding wheel is more and more wide, and the consumption is also more and more large. Ceramic bonded diamond grinding wheel has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, not easy to heat and block, small thermal expansion, easy to control machining accuracy, etc.

Grinding wheel is the most important grinding tool in grinding. Grinding wheel is a kind of porous body, which is made by adding binder into abrasive, pressing blank, drying and baking. Due to the different abrasive, binder and manufacturing process, the characteristics of grinding wheel are also very different, so it has an important impact on grinding quality, productivity and economy. The characteristics of grinding wheel are mainly determined by abrasive, particle size, binder, hardness, structure, shape and size.

According to the abrasives used, they can be divided into ordinary abrasives (corundum, silicon carbide, etc.) Grinding wheel, natural abrasive, super hard abrasive and grinding wheel (diamond, CBN wheel, etc.);

According to the shape, it can be divided into plane grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup grinding wheel, dish grinding wheel and so on. According to the different bond, it can be divided into ceramic wheel, resin wheel, rubber wheel, metal wheel and so on. The main characteristic parameters of grinding wheel are abrasive, viscosity, hardness, bond, shape, size, etc.

Grinding wheel is an important part of abrasive industry. Sand mold industry plays an increasingly important role in machinery production. Grinding wheel plays an indispensable role. With the development of science and technology, there are more and more new materials, and the processing is developing in the direction of high quality, high precision, high efficiency and automation. The application scope of ceramic bonded diamond grinding wheel is more and more wide, and the consumption is also more and more large. Ceramic bonded diamond grinding wheel has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, not easy to heat and block, small thermal expansion, easy to control machining accuracy, etc. Compared with resin bonded diamond grinding wheel, it solves the problems of low service life, low grinding efficiency and easy deformation of grinding tools.

According to the data of "2017-2022 China grinding wheel Market Analysis and investment prospects Research Report" released by Bosi, driven by downstream demand, the growth of global grinding wheel Market Supply and demand is slow. In 2015, the global output and consumption of grinding wheel were 2.763 million tons and 2.759 million tons respectively.
