As a replacement for the functions of traditional engines (gearboxes), the performance of electric motors and electronic control systems directly determines key performance indicators such as the climbing ability, acceleration, and maximum speed of electric vehicles. Therefore, the electric motor is the core of related technologies for new energy vehicles. Among them, a high-precision motor shaft is the key to ensuring stable and reliable motor transmission.

[0003] Currently, the mechanical processing technology for motor shafts with gear shaft segments usually combines conventional methods such as turning, grinding, and hobbing.

To improve the accuracy of the motor shaft, multiple mechanical processing methods are required, and the relationship between these mechanical processing methods is in series. There is still a large room for improvement in the mechanical processing technology to improve production efficiency. 3. During the processing, a large amount of metal chips are generated, which is not conducive to subsequent cleaning, easily causes pollution to the workshop environment, and generates respirable dust that poses a threat to the health of operating workers when inhaled into the body.
