High-efficiency machining solution for new energy vehicle drive motor shafts

2023-08-11

Drive motor shafts are subjected to alternating stresses such as torsion, shear, tension, compression, and impact during operation, and are subjected to large loads and torques. At present, other high hardness materials such as 20CrMnTiH materials are commonly used in the manufacture of motor shafts. In addition, the connecting parts at both ends of the shaft body need to be heat-treated to meet the requirements.



WSS offers turning, milling and holemaking tools for the complete machining of motor shafts with higher stability and reliability, which not only meets the high dimensional precision requirements for oil-filled holes, keyways and shallow holes in motor shafts, but also provides high surface quality after CBN hard turning.
