Type of adhesive
According to the types, it can be divided into inorganic binders and organic binders. Inorganic binders include ceramic binders, metal binders and magnesite binders. Organic adhesives include resin adhesives and rubber adhesives. The bonding strength of this binder to abrasive is better than that of resin. After the abrasive tool is formed, the surface of the workbench has good chip performance, is not easy to block, has sharp cutting, high grinding efficiency, small thermal expansion and easy control of machining accuracy, which is beneficial to the smooth grinding process. In the shaping and dressing of abrasive tools, it is relatively easy to operate, and is generally used for rough grinding, semi-fine grinding and large contact surface forming grinding.

Ceramic bond is a widely used bond. The stability of ceramic bonded diamond abrasive is good, and it has gained a good market and reputation in the field of ceramic bonded cubic boron nitride grinding wheel. When ceramic bond is combined with diamond abrasive, the difficulty coefficient is relatively large, which hinders the research and development of ceramic bond diamond grinding wheel. Engineers of Henan Shengchuang Superhard Materials Co., Ltd. have overcome the technical problems of poor heat resistance of diamond and low sintering temperature of ceramic binder. Engineers took the lead in producing ceramic bonded diamond grinding wheels for grinding gems in China, and formulated a variety of grinding wheel specifications, which were favored by the gem processing field. The series of ceramic bonded diamond grinding wheels developed before 20 12, such as grinding PCD/PCBN tool ceramic bonded diamond grinding wheel and grinding diamond composite ceramic bonded diamond grinding wheel, have gained a good reputation in the market. Include bronze adhesive and electroplating adhesive. Electroplating adhesive is a kind of adhesive with high bonding strength. Usually, single or multiple layers of abrasive particles are electroplated on a metal substrate. The number of abrasive particles per unit area of the working surface of this bond tool is much higher than that of other bonds, and the abrasive particles are exposed on the surface of the bond, so the cutting is sharp and the grinding efficiency is high. However, due to the limitation of coating thickness, the overall service life of abrasive tools is not high, and they are generally used for special-purpose processing, such as abrasive tools for forming grinding, small grinding heads, nesting knives, electroplating reamers and files. With the continuous progress of technical level, the application of cubic boron nitride electroplated metal bond abrasives is expanding day by day, especially when machining small holes and cavities of various steel parts, which not only has high grinding efficiency and good economy, but also can obtain better shape accuracy. The bronze bonded abrasive tool is made of copper powder and tin powder as the main raw materials, supplemented by other materials to supplement and improve its performance, then added with abrasive and mixed evenly, and then put into the mold for pressing and sintering. This kind of abrasive tool has high bonding strength with abrasive particles, good wear resistance and little wear, so it has a long service life and can maintain a good shape, so it can bear a large load. But the disadvantages are poor self-sharpness, easy surface blockage and high fever, which is very difficult to finish. It is mainly used for rough grinding, fine grinding and cutting of nonmetallic materials such as glass, ceramics, stone, building materials, concrete and semiconductor materials, and a small amount is used for grinding cemented carbide and composite superhard materials, as well as forming grinding, honing and electrolytic grinding.
