What should be paid attention to when opening the aluminum profile mold for industrial aluminum extrusion molds?

1. When opening the aluminum mold and cutting the extrusion mold hole working zone by wire, the current should be stable, so that the die hole size after cutting is uniform and the hole wall is flat;

2. When cutting the aluminum extrusion mold hole working zone, the current should not be too large to prevent the molten layer from being too thick, because the molten layer is one of the main reasons for the brittle peeling of the die hole working zone, and the processing discharge gap should be controlled at 0.01mm;

3. When the extrusion mold working zone is empty during EDM machining, the current should not be too large to prevent the machining surface from being burned. The discharge gap should be controlled at 0.05~0.1mm. When roughing the empty knife, remove the electrode and grind it flat at 1mm from the higher point of the working zone. According to the width of the die hole working zone, correct the working surface of the electrode into a curved surface (the surface is required to be flat and the roughness is low), change the polarity, and perform aluminum finishing 1. When opening the aluminum mold and cutting the extrusion mold hole working zone by wire, the current should be stable, so that the die hole size after cutting is uniform and the hole wall is flat.
