CSSM researches and develops a kind of double end spindle motor.
It is driven by the secondary motor which enables bi-directional processing on various materials with the speed of 5000rpm-24000rpm by the tools of φ3-φ13. It applies multi-level protection to ensure the long-term service life of the spindle motor. The ER20 is the major processing end which shall bear larger load, and the other end is the auxiliary processing end which shall bear smaller load. In this case, the double end spindle motor is durable!
