Characteristics of abrasive tools
Abrasive tool is characterized by a wide range of use, with a certain flexibility and a high bonding strength, and has a good polishing performance. The resin abrasive tool has the following characteristics in the rough, fine, fine, polishing and so on:
1, the combination of high strength
Compared with the ceramic bond, the resin bond strength is high, the grinding line speed of the resin grinding wheel is up to 80~120m/s, and can bear large grinding pressure. Heavy load grinding pressure up to 10 * 104 ~ 40 x 104n, widely used in iron and steel industry, such as shortage of all kinds of steel ingot, billet, etc, and grinding process. High speed heavy load special grinding wheel and other coarse grinding process is safe, it is suitable for high speed grinding and high feed grinding, high grinding efficiency.
2, with a certain flexibility
Relative ceramic abrasive tool has good toughness, there is a certain plasticity and ductility. Its modulus of elasticity (E) is several times lower than that of the ceramic. Therefore, the resin abrasive tool is suitable for the preparation of a variety of specifications of the thin grinding wheel and high speed cutting grinding wheel. At the same time, due to the elastic deformation, the effect of grinding force can be buffered. Therefore, the grinding effect is good, and the polishing effect can improve the roughness of the processing surface.
