[0002] Aluminum-clad enameled wire is a more commonly used type of enameled wire. Copper-clad aluminum enameled wire is a new type of electromagnetic wire that uses copper-clad aluminum as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent conductivity of copper and the light weight of aluminum. Copper-clad aluminum enameled wire is now widely used in high-frequency transformers, ordinary transformers, inductors, electromagnetic coils, motors, including household motors, various micro motors, compressors and other motors with high environmental requirements.

[0003] In the production process of copper-clad aluminum wire, the aluminum core needs to be processed to the required diameter before the copper layer is coated. The existing aluminum core processing method is to directly grind the aluminum core through a grinding device. A lot of metal debris and dust will be generated in the processing process, and the generated aluminum dust has explosion-related safety hazards.

Although the above device adopts a rotary cutting process to solve the problems of grinding dust, it is not convenient for cutting copper-clad aluminum wires of different diameters, and because the copper-clad aluminum wire is made of a relatively soft material, there is still a problem of easy deflection during rotary cutting.
