[0002] The motor is an important component of modern industry, which realizes the mutual conversion between electrical energy and mechanical energy. Its structure includes a stator and a rotor. The stator generates a rotating magnetic field, which acts on the rotor to form a magneto-electrodynamic rotational torque, making the motor rotate.

[0003] The rotor is usually composed of a rotor core with wound coils, slip rings, fan blades, etc. The commonly used processing methods for the rotor core include casting, pressing and forging. Pressing and forging are used to produce high-performance motors. Casting is a more traditional production method with low cost and relatively average performance. The surface of the rotor core formed by casting will have defects such as burrs and sand inclusions, and needs to be polished to improve its surface quality and precision and enhance performance. In the actual polishing process, it is more difficult to position the core, and the positioning coaxiality directly affects the accuracy of polishing. It is difficult to accurately control the holding force when the polishing part contacts the surface of the core. A large force will affect the dimensional accuracy and damage the edges and corners of the surface grooves, destroying the overall structure.
