Grinding wheel is a type of grinding tool used in machining processes such as grinding, cutting, grinding, and polishing, mainly composed of three parts: abrasive, binder, and porosity. Among them, abrasive is the main working part of the grinding wheel, which determines the cutting performance of the grinding wheel; Binders are materials that bond abrasives into the entire grinding wheel. Common binders include ceramics, resin, rubber, etc; Pores help to dissipate heat and remove debris during the grinding process.

To ensure the normal use of grinding wheels and extend their service life, regular maintenance is necessary. Regularly check the wear of the grinding wheel and replace severely worn grinding wheels in a timely manner. Before use, the surface of the grinding wheel should be cleaned to remove oil and impurities. When installing the grinding wheel, ensure the concentricity between the grinding wheel and the spindle to avoid vibration and noise. During use, attention should be paid to controlling the grinding pressure and speed to avoid excessive wear and damage to the grinding wheel. When storing grinding wheels, they should be placed in a dry and ventilated place, avoiding direct sunlight and humid environments.
