1. The current should be stable when the working belt of the die hole of the aluminum material is opened and the wire cutting extrusion die is used, so that the size of the die hole after cutting is uniform and the hole wall is flat;
2. When cutting the working belt of the die hole of the aluminum extrusion die, the current is not easy to be too large to prevent the molten layer from being too thick, because the molten layer is one of the main reasons for the brittleness and peeling of the working belt of the die hole, and the machining discharge gap is controlled at 0.01mm;
3. When the EDM extrusion die is working with an empty knife, the current is not easy to be too large to prevent burns on the processing surface, and the discharge gap is controlled at 0.05~0.1mm. When roughing the empty knife, remove it when it is 1mm higher from the working belt. Polish the electrode, correct the working surface of the electrode into a curved surface according to the width of the working belt of the die hole (it is required to have a flat surface and low roughness), change the polarity, and perform aluminum finishing 1. Aluminum mold opening, wire cutting extrusion When pressing the working belt of the die hole, the current should be stable, so that the size of the die hole after cutting is uniform and the hole wall is flat.
