Abrasive tools are for grinding and polishing. Most of the abrasive tools are artificial abrasives made of abrasives and bonding, and natural abrasives are also directly processed from natural ore. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as food processing, paper industry, ceramics, glass, stone, plastic, rubber, and wood.

During the use of the abrasive tool, when the abrasive grains are blunt, the abrasive grains partially or completely fall off from the abrasive tool due to the partial fragmentation of the abrasive grain itself or the breakage of the bonding agent, and the abrasive material on the working surface of the abrasive tool continuously appears new cutting edge, or constantly revealing new sharp abrasive particles, enables the abrasive tool to maintain cutting performance within a certain period of time. This kind of self-sharpening of abrasive tools is the outstanding feature of abrasive tools compared with general tools.

There are two manufacturing processes for metal bond abrasive tools, powder metallurgy and electroplating, which are mainly used for super-hard abrasives to consolidate abrasives. The powder metallurgy method uses bronze etc. as the binder, and after mixing the materials, it is formed by hot pressing or pressure at room temperature, and then sintered. The electroplating method uses nickel or nickel-cobalt alloy as the electroplating metal, and the abrasive is fixed on the substrate according to the electroplating process to make abrasive tools.

Resin bond abrasive tools are generally molded on a press at room temperature, and there is also a hot pressing process that uses heating and pressure under heating conditions. After molding, it is hardened in the hardening furnace. When phenolic resin is used as the binder, the curing temperature is 180 to 200°C.

Rubber bond abrasive tools are mainly mixed with a roller machine, rolled into thin sheets, and then punched out with a punching knife; some loose materials are put into a metal mold and formed on a press. After molding, it is vulcanized in a vulcanizing tank at a temperature of 165-180°C.
