Electrochemical deburring is to use electric energy and chemical energy to dissolve the anode of the part to remove the burr. The part is the anode, which is connected to the positive electrode of the power supply, and the electrode is the cathode, which is connected to the negative electrode of the power supply. A certain gap is maintained between the two electrodes, and the electrolyte circulates and takes away the electrolysis products; when the two electrodes are connected to the power supply, an electrochemical reaction occurs on the surface of the anode in the electrolyte, and the metal on the surface of the workpiece is dissolved; and the processing gap where the burr protrudes from the surface of the workpiece is significantly smaller than the gap in other parts of the workpiece. After power is turned on, the power lines are highly concentrated on the burr part. The burr closest to the cathode will be dissolved at the fastest speed until the burr is completely dissolved and the edge gradually forms a rounded corner, thus achieving the purpose of deburring. Electrochemical deburring is not limited by the hardness of the material, and is suitable for removing burrs of high-hardness and high-toughness metal parts. It can also remove burrs in complex inner cavity parts that are difficult to handle manually and have poor accessibility, especially burrs of the intersection line of cross holes.
