Abstract The design of machine tool spindle for minimum cylindricity error is presented. The shape of the spindle portion between the bearings, usually cylindrical, is reconfigured to increase the spindle rigidity. Two methods of reconfiguration are presented. In the first method, the spindle is reshaped as a smooth body of revolution. In the second method, the spindle is reshaped as a stepped shaft. Effects of bearings rigidity and fatigue stresses are also considered.
