Abstract
A cylindrical blank is mounted on the turn table of a vertical lathe with the axis of the former as close as possible to the axis of the latter. The angle between a reference point on the periphery of the blank and a measuring point circumferentially displaced from the reference point and the deviation of the periphery at the measuring point from a circle about the axis of the turn table are measured. Then an axis at which the dispersion of the deviation at the measuring point is a minimum is calculated by using the measured angles and the deviations to determine the distance between the axis of the blank and the axis of the turn table, and press members mounted on the turn table are actuated to move the blank by the distance thus determined to coincide the axis of the blank with the axis of the turn table.
