The resin binder has a higher bonding strength than the ceramic binder, and the manufactured abrasive has higher mechanical strength than the ceramic abrasive. It can be used at higher speeds, can withstand large grinding pressure, and is safe to operate. It is widely used in the rough grinding process of steel, automobile bearings, chemical machinery, construction, and other industries. The resin is a polymer compound with a certain toughness and elastic deformation, which can buffer the grinding pressure, so the grinding effect is good, and it has a good polishing effect, which can improve the surface processing quality of the workpiece. With the emergence of new types of resins, resin grinding tools of various strengths and properties can be made, which can be used for grinding, rough grinding, cutting, semi-finishing, fine grinding, polishing and the like. The resin binder has a low curing temperature and a small shrinkage rate and can be made into various complicated shapes and special requirements. Such as a round grinding wheel, plus a high-speed 125*1*22 EN12413 cutting disc of mesh cloth. The resin binder has low heat resistance and is easily charred by heat during the grinding process, which promotes the blunt abrasion of the abrasive grains, reveals new sharp abrasive grains, reduces the heat of the grinding area, and avoids burns of the workpiece; therefore, Suitable for surface grinding, etc., but the wear is greater than ceramic abrasives. The resin grinding machine has a short production cycle, simple equipment investment, fast capital turnover, and high production efficiency, which is beneficial to professional production. Generally, the resin abrasive has poor alkali resistance and water resistance and cannot be stored for a long time. In the case of alkaline substances, the resin structure degrades, affecting the strength and hardness of the abrasive. In addition, resin abrasives are expensive and have a poor production environment.

Resin abrasives are used in a wide range of applications. The grinding wheel is mainly used in the steel industry for the grinding of steel ingots, billets, steel plates and surface cleaning of various castings. From the production point of view, it ranks first in various resin abrasives. The high-speed cutting piece is developed on the basis of the ordinary aluminum flat cutting disc according to the grinding process requirement. The speed is 70-80M/S, which has the advantages of high cutting efficiency, good impact resistance and bending resistance. At present, it has been developed from cutting small metal materials to cutting large-size steel and steel plates. The specifications of grinding wheels are increasing and the output is getting bigger and bigger, second only to the grinding wheel. High-speed grinding discs are widely used in the grinding of welds in metallurgical, chemical, shipbuilding and other mechanical processing industries, cleaning of casting burrs and metal surfaces. The product has many specifications and the speed of use is 60-80M/S. It is widely used in the grinding industry of automobiles, tractors, and bearings. Its outstanding feature is the use of surface grinding technology. It can be made into a non-shaped abrasive such as an atmosphere, a grinding wheel or a slotted grinding wheel, which greatly improves the grinding performance of the grinding wheel. In addition, some resin grinding wheels are also widely used in various industries, replacing ceramic grinding wheels and rubber grinding wheels to varying degrees.
