Abstract The compensation system for the spindle elongation of high-speed NC machine tool is designed and implemented in this paper. The analysis of high-speed spindle elongation principle is presented. And the specifi c measures and implementing methods of axis compensation are put forward, and PLC controlling program is made. Test data shows the feasibility of this compensation method. Application of this method improves the machining precision, and this method can be promoted widely.
