The existing technologies for solving the problem of chip entanglement on the tool are all indirect methods. For example, increasing tool air blowing and tool high-pressure water flushing. The air blowing method can only clean the residue at the tool tip and cannot clean the filamentous and ribbon-shaped iron chips. For tool high-pressure water flushing, a working pressure of more than 7 MPa is required to achieve chip breaking. However, the entire high-pressure system has a complex structure, and the tool needs to be customized with a center water outlet type, which is costly. Therefore, in order to solve the above problems, it is necessary to make improvements. Content of the Utility Model
