Description of the main points of aluminum extrusions:
1. The current should be stable when cutting the working hole of the die of the wire cutting extrusion die so that the size of the die hole after cutting is uniform and the whole wall is flat;
2. The current should not be too large when cutting the working hole of the die of the aluminum extrusion die, to prevent the molten layer. Excessively thick, because the molten layer is one of the main reasons for the brittle spalling of the working hole of the die hole, the processing discharge gap is controlled at 0.01mm
3. When the EDM extrusion dies works with an empty knife, the current is not easy to be too large to prevent For burnt working surface, the discharge gap is controlled at 0.05 ~ 0.1mm. When rough punching the knife, remove the electrode and flatten it at a height of 1mm from the working belt. Correct the working surface of the electrode to be curved according to the width of the die hole working belt The surface is flat and the roughness is low), the polarity is reversed, and finishing is performed, which can ensure that the processing is in place, and the vertical surface of the empty knife is smooth and flat, reducing the surface mold line of the product.
