Abstract: A device is disclosed for advancing a workpiece in automatic processing by a wire erosion machine. A part of the workpiece which is not to be processed is clamped to a clamp bearing at a cross-coordinate point. The part of the workpiece which is to be processed rests on a bearing table which is displaceable in two directions of movement. The bearing table, which possesses the same height as the clamp bearing, is provided with a slot through which the electrode can be passed. In the one direction of movement the bearing table is moved by the support, whereas in the other direction of movement the support slides along one side of the bearing table and the workpiece slides along the bearing table.
