【Abstract】 High Speed Machining (HSM) is one of the High Technologies,which is the second revolutional change after numerical control in manufacturing.It hsa not only the high productivity, but also has the high machining accuracy and high surface quality. In this paper, the developing status of HSM is introduced.Two key techniques high speed motorized spindle and high velocity feed unit driven by linear motor are given. The application and developing prospect of HSM are discussed as well.更多还原
