What does the number of grinding wheel mean?

You can often see the mesh number of the grinding wheel when using or purchasing the grinding wheel. So which numerical parameter does this number represent? Today, the editor of CNDOME abrasive wheel will give you some popular science.
The mesh number of the grinding wheel refers to the size of the abrasive grain size. According to the size, it is divided into abrasive grains and fine particles. The particles with a particle size larger than 40 μm are called abrasive particles. Those smaller than 40μm are called particles. A 60-mesh grit is just sized to pass through a screen with 60 holes per inch of length. 600 mesh is the size of the abrasive particles that can pass through a screen with 600 holes per inch of length.
The mesh number of the abrasive wheel is mainly related to the roughness of the workpiece surface during grinding. When rough grinding, the grinding allowance is large, and the required surface roughness value is also large. Therefore, use a abrasive wheel with a smaller mesh. In this way, the abrasive wheel is not easy to block and heat up. The roughness value of the workpiece surface during fine grinding is low. The abrasive wheel with a larger mesh should be selected. The finer the abrasive grains, the better the surface roughness of the workpiece.
The above is the meaning of the mesh number of the abrasive wheel. When purchasing abrasive wheels, you can also grind according to the workpiece you want to grind. And the grinding effect you want to achieve to select the appropriate abrasive wheel.
