The resin bond has higher bonding strength than ceramic bond, and the abrasive tool has higher mechanical strength than ceramic abrasive tool. It can be used at a high speed and can bear greater grinding pressure and safe operation, so it is widely used in the rough grinding process of steel, automobile bearing, chemical machinery, building and other industries. Resin is a polymer compound, with a certain toughness and elastic deformation, can buffer grinding pressure, so the grinding effect is good, good polishing effect, can improve the quality of the workpiece surface processing. With the emergence of new resin, we can make various strength and properties of the resin grinding tools, can be used for grinding, grinding, cutting, semi fine grinding, fine grinding, polishing and other grinding tools. The resin bond has low hardening temperature and small shrinkage, and can be made into various abrasive tools with complex shapes and special requirements. For example, cymbal wheel, high speed cutting piece with grid cloth. The resin binder has low heat resistance, and is easily carbonized during grinding, prompting the grinding blunt abrasive particles to fall off automatically, exposing new sharp abrasive particles, reducing the heat of the grinding area and avoiding the workpiece burn; therefore, it is more suitable for plane grinding, but the wear is greater than the ceramic grinding tool. Resin grinding tools have short production cycle, simple equipment, less investment, fast turnover of capital, and high production efficiency, which is conducive to professional production. The general resin Abrasives have poor alkali resistance and water resistance and can not be stored for long. When the alkaline substance is found, the structure of the resin is degraded, which affects the strength and hardness of the abrasive tool. In addition, resin abrasives are expensive and the production environment is poor.
The application of resin grinding tools is very wide. Rough grinding wheels are mainly used for grinding steel ingots, billets, steel plates and surface cleaning of various casting parts in the steel industry. Judging from its output, it occupies the first place in all kinds of resin abrasives. The high speed cutting plate is developed on the basis of the requirements of the grinding process. The speed 70-80M/S is used. It has the advantages of high cutting efficiency, good impact resistance and bending resistance. At present, it has been developed from cutting small metal material to cutting large size steel and steel plate. The size of the grinding wheel is more and more, and the output is getting bigger and bigger. It is second only to the barren grinding wheel. High speed abrasive discs are widely used in metallurgy, chemical industry, shipbuilding and other mechanical processing industries, such as grinding weld, cleaning burr and metal surface. The specifications of the products are many, and the use speed of 60-80M/S. is widely used in the grinding and processing industries, such as automobiles, tractors and bearings. It is characterized by the use of plane grinding technology. It can be made into abrasive tools such as air, grinding wheel, slotting wheel and so on, which greatly improves the grinding performance of grinding wheels. In addition, some resin grinding wheels are also widely used in all walks of life, replacing ceramic grinding wheels and rubber grinding wheels to varying degrees.
