Classification and characteristics of common grinding wheel materials

Resin bond grinding wheel

Generally, the most widely used cutting discs and polishing discs use resin binders. It is characterized by high bonding strength, easy operation, good elasticity, and a certain polishing effect. Because the resin is not resistant to high temperature during use, the bonding agent is easy to burn, so that the abrasive can contact the workpiece more, and also ensure the sharpness of the grinding wheel. It can reduce the burn of the workpiece. The grinding temperature of this bond grinding wheel is not as high as that of the ceramic, and the swiss machining time is shorter.

Rubber bond grinding wheel

The elasticity is greater than the resin binder, and the polishing performance is good. It is not easy to burn the workpiece when it is used. It is especially suitable for fine grinding or polishing. Generally, synthetic rubber is used as a binder. The firing temperature is low and the production cycle is short, but the structure is tight, the pores are small, and the oil resistance is poor. It is not suitable for general roughing, and oil grinding fluids cannot be used when grinding.

Ceramic bond grinding wheel

It is mainly made of ceramic-like mineral raw materials by high-temperature firing. It has a wide range of use, and has stable chemical properties and good heat resistance. It will not be affected by the high temperature during swiss cnc machining and the nature of the grinding fluid used to change the composition. Its elasticity The deformation is small, most of the grinding wheels are made of ceramic bond. However, because this binder must be fired at high temperature, the requirements for abrasives are higher and the production cycle is longer.

Metal bond grinding wheel

It is mainly used to manufacture grinding wheels using super-hard abrasives. Because the hardness of super-hard abrasives is high, combined with metal bonding agents, it can play its advantages of sharpness and wear resistance. It is mainly made of copper, tin, iron, etc. as a binder. The powder metallurgy or electroplating swiss machined is used to bond (sinter) the abrasive and the binder with high strength, so as to firmly hold the abrasive particles and maintain the shape and strength of the grinding wheel. Extended service life.
