| Abstract: | Heat generation and deformation are key factors that influence the rigidity and machining accuracy of the high-speed precision spindle system. In this paper, a temperature field model is built for the system of bearings?spindle and bearing house as a whole, temperatures of key nodes are calculated and affection of the factors such as speed?machining force and lubrication methods on the node temperature are analyzed. |
