The high speed large power precision motorized spindles are core components of high speed NC machines. And the general development level of high speed NC machines is decided by the behaviors of the spindles to great extent. The developments of the technology in worldwide area were reviewed in this paper. Several key techniques of high speed large power precision motorized spindles are introduced systematically and deeply, and the develop ment tendency of the spindle technology are forecasted.
