Disclosed is an alignment system for a vertical lathe, the lathe configured to perform a cutting process on a workpiece (W) mounted on a circular turn table () by rotating the workpiece (W), and the alignment system configured to, when the lathe performs the cutting process on an unbalanced eccentric workpiece, perform a center alignment operation for correcting imbalance. The alignment system includes an alignment mechanism which includes: multiple alignment weights () provided movable along an outer periphery () of the circular turn table (); and a movement mechanism () configured to move the alignment weights along the outer periphery () of the turn table (). The alignment system further includes a control unit () configured to calculate setting positions for the alignment weights (), and to set the alignment weights () at the calculated setting positions using the movement mechanism (), in order to correct the imbalance.
