<p>This multi-spindle automatic lathe (10) is provided with: a spindle carrier (102) that rotates in an indexed manner; a plurality of main spindles (103) that are disposed on the spindle carrier (102) and that hold and rotate a workpiece; and a plurality of cross-slides (11) that have a blade (16) for machining the workpiece and that can move along the direction that approaches toward and separates from each main spindle (103). The cross-slides (11) machine the workpiece by moving along the direction that approaches toward and separates from each main spindle (103) within any given angle range by means of an eccentric cam (13) that is driven to rotate by a servo motor (21). As a result, it is possible to easily and accurately correct workpiece machined dimension errors stemming from differences in the distance from the rotational center of the spindle carrier and the rotational centers of each main spindle.</p> |
