[0002] In the process of machining mechanical parts, it is often necessary to use machining tools to machine the surface of the parts. The existing machining tools are prone to the problem that the machining roughness cannot meet the machining requirements during the machining process. Especially after the machining tools have been working for a long time, it is very easy for the machining parts with machining requirements lower than the roughness Ra1 to be processed. Since the roughness of the machining parts is too small, the existing machining tools cannot be used; for machining parts with a roughness higher than Ra2, the machining tools need to be re-ground, which makes the entire machining process time-consuming and labor-intensive, and cannot effectively improve the production efficiency of the enterprise. In view of this, it is particularly important to find a machining tool structure that has a simple structure, stable operation, and can be adjusted according to machining needs;
