The invention discloses a washing machine motor rotor production process, comprising the following steps: S1: stamping; S2: casting aluminum, setting the temperature of a resistance melting aluminum furnace, and preheating, then adding pure aluminum into the resistance melting aluminum furnace, Put the stamped rotor into the cast aluminum mold, start the cast aluminum hydraulic press, and carry out the cast aluminum operation of the rotor. After the end, inspect the cast aluminum rotor to determine whether it meets the requirements; S3: Finale, press the shaft into the cast aluminum rotor ;S4: Turning, place the rotor on a lathe, and perform turning operation. After the turning operation is completed, perform surface runout detection, and clean up the burrs and aluminum cutting flashes of the rotor; S4: Perform surface processing, and complete the entire Rotor production process. The motor rotor proposed by the invention has a perfect production process, a clear process, high detection accuracy of key procedures, accurate evaluation of the quality of the motor rotor, and ensures that the produced rotor has good quality, stable performance and long service life.
