In the manufacturing of new energy vehicle battery modules, the dimensional accuracy of the battery shell processed by CNC can reach ±0.05mm, and the flatness of the electrode connecting parts is controlled at ±0.03mm, which greatly improves the structural stability of the battery pack and the reliability of the electrical connection. For solar photovoltaic equipment, CNC machining parts can increase the light energy conversion efficiency by 5%-8%, helping the new energy industry to accelerate towards efficient and stable direction.
