The introduction and use of the characteristics of the wheel

Wheel is binding agent with many small flange or corners mineral crystal particles cemented together to form. Wheel hardness than particles is grinding and cutting tools, but also the need to have sufficient strength and flexibility, we can resist the impact force generated by the grinding process. These particles are obtained after crushing abrasive.
The abrasive is made from natural and man-made abrasive abrasive material commonly used natural abrasive corundum, emery. Artificial Abrasive ordinary alumina, white alumina, black silicon carbide, green silicon carbide. The size of the abrasive particles called concrete cutting wheels size.
Grindstone at work due to the surface of the particles and the friction between the cutting tool, it will gradually wear blunt, when the grinding resistance beyond the adhesion between particles and a binder, the particles began to fall off, and was replaced by new sharp particles. So the wheel has a self-sharpening performance. But adhesion binding agent should not be too strong, too strong as particles after blunting also attached to the wheel surface grinding wheel will lose effect. Further, since the granite cutting disc and the workpiece is friction will have a lot of heat, the binding agent can easily be softened. By grinding the metal material at the end of the adhesive binder filled with sand in the cracks between the wheel stopper reality. If this plug solid wheel continues to work, not only relatively low efficiency, are causing annealing grinding and cutting tools also become blue. On the other hand if the binding agent is not firmly bonded particles in the particle has not been changed between the pure grinding but also will make it fall off, so wear faster transmission lines sand, easily deformed, require regular trimming.
