[0002] With the continuous improvement of environmental protection requirements and the continuous reduction of non-renewable energy, the new energy vehicle industry has become a hot industry. New energy vehicles require good endurance and low cost. The lighter the quality of the car and its parts, the better, and the lower the cost, the better. The requirements for lightweight and low cost are getting higher and higher. Therefore, a water-cooled motor with higher power density has gradually emerged. The water jackets of water-cooled motors are varied, but now all water jackets are produced by aluminum extrusion technology.

[0003] The inner hole of the motor water jacket needs to be fine-bored by a milling machine during the processing process. However, since the balance between the inner hole and the end face of the motor water jacket needs to be ensured during the boring process and the tolerance value needs to be within 5 wires, the existing motor water jacket needs to be fixed on the milling machine for multiple times, resulting in low processing efficiency, and multiple processing causes the motor water jacket to shift.
