The invention relates to an automated manipulating appliance for feeding workpiece blanks from a store to a numerically controlled machine tool with an automatic clamping fixture and for removing the machined workpieces from the machine tool to a store. The manipulating appliance consists of a numerically controlled transport device with a longitudinal support on which a slide is mounted in a horizontally displaceable manner. A vertical arm is displaceably connected to the slide. Two parallel, horizontal gripper arms are in turn displaceably connected to the vertical arm. The gripper arms are connected independently of one another at right angles to the longitudinal support and in each case carry a gripper at the free end. The slide, the vertical arm, the two gripper arms and the two grippers are provided with numerically controlled drives. The transport device is programmed in such a way that, after a workpiece is machined, the two grippers are arranged near the clamping fixture, one gripper being empty and therefore ready to receive the machined workpiece, whereas the other gripper is equipped with a workpiece blank in order to transfer the latter to the clamping fixture.
