[0020] Tools used for machining the ring grooves of conductive ring assemblies, such as Figures 1-3 As shown, the assembly includes a tool holder 1 and a cutting head 2 located at the end of the tool holder 1. The tool holder 1 is a rod-shaped structure with a rectangular cross-section. The cutting head 2 includes a V-shaped cutting edge 2-1 at the lower end and right-angled grooves 2-2 symmetrically arranged on the inclined walls on both sides of the V-shaped cutting edge 2-1. The V-shaped cutting edge 2-1 is used to machine a V-shaped groove 4 on the conductive ring assembly 3, and the right-angled grooves 2-2 are used to machine a square groove ring 5 on the conductive ring assembly 3. Specifically, the tool holder 1 and the cutting head 2 are an integral structure.

[0022] After the conductive ring assembly 3 is glued once, the conductive ring assembly 3 is installed on the lathe, the lead-out wire of the conductive ring assembly 3 is wound on the chuck and fixed with rubber bands, attention is paid to protect the lead wire, the lathe is started, the conductive ring assembly 3 is rotated, and the cutter is sequentially machined according to the ring groove, the ring groove is machined according to the required machining size, and the V-shaped groove 4 and the square groove ring 5 are formed by one-time machining.

[0023] The technical scheme has simple structure, novel design, accurate positioning, no need to frequently replace cutters, improved work efficiency, reduced cost, effectively shortened machining cycle of the ring groove of the conductive ring assembly, and improved machining quality.
