Many materials spark -erosion machining electrode

The utility model discloses a many materials spark -erosion machining electrode, include the electrode matrix and set up in the component galvanic corrosion material of electrode matrix bottom, the galvanic corrosion material of constituteing component galvanic corrosion material has more than one kind to resistant galvanic corrosion degree between the multiple galvanic corrosion material is different, and the resistant galvanic corrosion degree of galvanic corrosion material between with the electrode matrix is different, connect pulse generator's positive pole, negative pole respectively when electrode matrix and work piece, component galvanic corrosion material bottom surface forms fine complicated curved surface. Many materials spark -erosion machining electrode, utilize the fine complicated curved surface of spark -erosion sinking method processing, avoided traditional layering milling process inefficiency, frequently change the electrode and need to adopt loaded down with trivial details cutter path pla
