[0002] With the development of modern industry, the processing demand for hard and brittle materials such as cemented carbide, ceramics, glass, and gemstones is increasing day by day. These materials have the characteristics of high hardness, high brittleness, and difficult machinability. Traditional grinding tools are difficult to meet their processing requirements. Diamond grinding wheels have become an ideal choice for the processing of hard and brittle materials due to their excellent performance. For example, in the manufacture of cemented carbide tools, high-precision grinding processing is required for cemented carbide inserts to ensure the cutting performance and service life of the tools. Diamond grinding wheels can effectively grind cemented carbide, improving processing efficiency and quality.

[0003] In the prior art, the grinding wheel detection device is not convenient to carry. At the same time, it does not have an anti-slip function.
