The mesh number of the diamond grinding wheel for grinding tools should be determined according to factors such as the hardness and roughness of the grinding object. It is generally recommended to choose a diamond grinding wheel with a mesh of 150 to 320 for grinding.

1. Principles for selecting the mesh number of diamond grinding wheels

Diamond grinding wheels are a commonly used grinding tool, widely used in metal, ceramics, glass, stone, carbide and other fields. The mesh number of diamond grinding wheels is also one of the important factors affecting the grinding effect. The higher the mesh number, the finer the grinding effect, but the grinding speed will be reduced accordingly. Therefore, the mesh number of the diamond grinding wheel needs to be determined according to factors such as the hardness and roughness of the grinding object.

For materials with higher hardness or rougher surfaces, it is necessary to select a diamond grinding wheel with a lower mesh number for grinding, so that the hardness and protrusions on the surface of the material can be removed faster and the grinding efficiency can be improved. For materials with lower hardness or smoother surfaces, it is necessary to select a diamond grinding wheel with a higher mesh number for grinding to ensure a finer and smoother grinding effect.

2. The influence of diamond grinding wheel mesh on grinding effect

In order to understand the influence of diamond grinding wheel mesh on grinding effect more specifically, we conducted an experimental comparison. Under the same grinding conditions, different mesh diamond grinding wheels were used to grind cemented carbide, and the surface finish and processing speed after grinding were compared.

The experimental results show that under the same grinding force and time conditions, the grinding effect increases with the increase of diamond grinding wheel mesh, that is, the higher the surface smoothness, the slower the grinding speed. When the mesh of the diamond grinding wheel exceeds 320 mesh, the effect of improving the grinding effect is very small, so it is generally not recommended to use a higher mesh diamond grinding wheel for grinding.

In general, using a diamond grinding wheel with a suitable mesh for grinding can improve grinding efficiency and work accuracy, and is an indispensable part of modern processing.
