    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.

    (54) DEVICE FOR ELECTROUSING EFFICIENCY CUTTING The invention relates to the electroerosive treatment of an article by an electrode tool that is rewound during processing. Devices are known in which the electrode-tool nponycxatoT into a prefabricated hole in the product is equipped with a follow-up drive, which moves the table with the product along two mutually perpendicular i.lj guides. The disadvantage of this device is that in the last stage of the cutout, The cutout material falls off. As a result, fuss. KcuoT in the details of the place of burning, short,. Kie closures and there is a breakage of the electrode, which leads to marriage. In the event of a short circuit, it stops cutting the contour automatically. The maintenance staff must carefully monitor the contour cutting in the subsequent part processing stage. The purpose of the invention is to create an electroerosion treatment facility using a wired electrode, in which the erosion process eliminates the possibility of peeling off the cut material, as well as the resulting burnout and short circuits. The goal is achieved by the fact that the device is equipped with an additional plate, on which one guide is fixed, along which the table can move along the additional one. The plate, the supporting surface of the plate is in the same plane with the surface of the table and in the additional plate. Those have a slot through which the electrode-tool can move, the slot being parallel to the second guide, and the additional plate with the table can move in the second guide. In addition, the supporting surface of the additional plate is covered with a layer of Teflon. The device has the advantage that the possibility of falling out or falling off of the cut-out part of the part is eliminated and there is no burn-up point and short circuits. This advantage is especially noticeable when processing parts of large thickness. In addition, the reliability of the device gives the possibility of refusal of control by the staff on the performance of the part in the last stage of its processing. Each contour is automatically completed. Based on this, the device is suitable for automatically positioning and inserting the wire electrode into the initial opening of the next loop. The device allows automatic machining of parts with (many openings and complex outer contours.
    The drawing shows the device.
    The device comprises a plate 1 with a supporting surface 2 located directly below the part 3. The device has guides 4 and 5. The guide 4 is rigidly connected with plate 1, along which the table b moves along it in the x direction, on which the non-machining part is attached parts 3, and along guide 5 in Direction y, plate 1 moves together with table 6.
    The device has a counter-support 7, which provides the direction of the table b as it moves relative to the plate 1. In plate 1, a slot 8 is made parallel to guide 5. Electrode-tool 9 is missed through target 8, cutting contour 10 in part 3. Electrode-tool 9 is withdrawn behind the part and there either is wound onto a drum or cut into small pieces that are assembled in mWK. During processing, the table 6 with the plate 1 and the part 3 moves in the y direction, while the electrode tool 9 moves freely in the slit 8, the perpendicular movement of the part 3 together with the table 6 performs in the x direction while the part 3 slides along the supporting surface 2 plates 1.
    All sliding surfaces are teflon coated to reduce the coefficient of friction.
    The program specified in the control device, it is advisable to carry out in such a way that the last step was as far as possible in the y direction. Since the table with the part moves in the y direction in this case, the possibility of displacing the cut part in the part 3 is excluded.
