A workpiece changing mechanism for a numerically controlled lathe having a work spindle, a turnings guard and a turret in which a tool centering recess is provided and which is arranged to be moved in a direction essentially parallel to the axis of the work spindle. The workpiece changing mechanism comprises a first workpiece transfer device, a second workpiece transfer device and a workpiece gripper. The workpiece gripper is located, and preferably fixed, in the centering recess in the turret and is operable to transfer workpieces from the first workpiece transfer device to a work fixture of the lathe and from the work fixture to the second workpiece transfer device, and the first and second workpiece transfer devices are movably mounted within the turnings guard on the operating side of the lathe.
