Polishing method for cutting edge of high-smoothness chamfering tool

The invention relates to the technical field of cutting edge polishing of tools, in particular to a polishing method for a cutting edge of a high-smoothness chamfering tool. According to the scheme, the polishing method for the cutting edge of the high-smoothness chamfering tool comprises step S1, a trimming wheel is used for trimming the axial end face of a grinding wheel, so that the axial end face of the grinding wheel is a plane; and S2, polishing treatment is conducted on the cutting edge of the high-smoothness chamfering tool by using the axial end face of the grinding wheel, wherein thegrinding wheel moves in the radial direction when the grinding wheel is used for polishing the cutting edge of the high-smoothness chamfering tool, so that the axial end face of the grinding wheel carries out polishing treatment on the cutting edge along different parts of the radial direction. According to the technical scheme, when the cutting edge of the tool is polished, the whole axial end face of the grinding wheel
