Thermal and electrical spindle cooling due to electric spindle motor integrated in the spindle motor spindle unit Jinhua prices, and high speed, it will generate a lot of heat during operation, causing electric spindle temperature Jinhua electric spindle production, so that spindle dynamic characteristics deteriorate, thus affecting the normal operation of electric spindle. Therefore, we must take certain measures to control spindle temperature to a constant within a certain value. The general machine cycle oil cooling coercive manner spindle and spindle bearing stator cooling oil cooling oil is about to go through a mandatory cooling device outside the stator in the spindle and spindle bearing outer loop, take away the heat generated by high speed rotation of the spindle . Spindle usually hybrid bearing, composite ceramic bearings or electromagnetic levitation bearings. Hybrid bearing with high stiffness and damping, can greatly improve the processing efficiency, processing quality, longer tool life, reduce processing costs, which probably infinitely long bearing life. Composite ceramic bearings currently used in many electric spindle cell spindle, which use hot rolling element bearing Si3N4 ceramic ball bearing rings still steel, high degree of standardization, structural alterations of the machine is small, easy to maintain. Good electrical magnetic bearing spindle speed performance Jinhua electricity supply, high precision, easy to implement on-line monitoring and diagnosis, but due to the complexity of the electromagnetic measurement and control system, the bearings are very expensive, and the long-term high, has not been widely used.
