A lathe work center device centers a workpiece about an axis of rotation on a lathe. The lathe has two tool centers with at least one tool center being driven and both tool centers coaxially positioned about the axis of rotation. The work center device includes a substantially flat main ring portion having an outer periphery. A plurality of spurs integral with the main ring portion project toward and are embedded within the workpiece. The spurs are positioned on a side of the ring portion that is adjacent to the workpiece, proximate the outer periphery. A centering portion integral with the main ring portion projects outwardly therefrom on a side of the main ring portion opposite the spurs. Preferably, the centering portion has a frusto conical configuration and engages the tip of a tool center, locating the workpiece about the axis of rotation. A plurality of lugs proximate the outer periphery engage cooperating slots in the driven tool center for rotating the workpiece.
