An apparatus for rotating a workpiece in a machining operation, the workpiece having internal passageways, includes a stationary support, a carriagemounted for reciprocation with respect to the support and a cylindrical shaft carried by the carriage and capable of rotary motion about its axis. A pinion gear is fixed to one end of the shaft and meshes with a rack which reciprocates in a direction perpendicular to the direction of the shaft axis. A pin carrier block is fixed to the other end of the shaft, and supports a plurality of pin members adapted to register with the passageways of the workpiece when the carriage moves from one extremity of its travel to the other. Once the pin members are engaged, the rack moves along its path in order to rotate the shaft, and thus the workpiece, through 90° to prepare it for further machining operations.
