[0016] 1. Even if the machine tool using this grinding head has no scale, it can still make the grinding depth of the processed products consistent.

[0017] 2. The grinding head is simple and reliable to use, and can effectively ensure the consistency and processing quality of the products after grinding.

[0018] 3. In this case, the outer diameter of the clamping handle of the grinding head can be set in sections according to the actual clamping range of the tool handle and the depth required for grinding. After the section setting, it can be combined with the grinding depth control part.
