The technology of deburring machine is to use electrical and chemical energy to dissolve the anode to remove burrs. The mechanical part is connected with the positive electrode of the electrolysis power supply as the anode, and the forming tool is connected with the negative electrode of the electrolysis power supply as the cathode. A certain gap is maintained between the two electrodes to allow the electrolyte to circulate. When the anode and cathode are immersed in the solution and connected to electrolysis, an electrochemical reaction occurs on the surface of the anode. The dissolved metal on the surface of the mechanical part and the electrolyte form a viscous liquid concentrated on the low recesses on the surface of the mechanical part, which has a high resistance and Less corrosion; while the burr protrudes on the surface of the mechanical part, it is difficult to form a liquid film under the influence of temperature difference. After power on, the power line is highly concentrated on the burr part and the burr closest to the cathode will dissolve at the fastest speed until the burr is completely dissolved and the edge Gradually form rounded corners to achieve the purpose of deburring.
Deburring machine tools can be used to make special fixtures (tool cathodes) similar in shape to the mechanical parts according to the structure of the mechanical parts, made of conductive materials such as brass or copper, and the unprocessed parts are coated with epoxy resin for isolation protection. Commonly used electrolytes include nacl, nano2> and nano>3 solutions. This technology is suitable for non-ferrous and ferrous metal mechanical parts, especially for mechanical parts with complex shapes and internal holes, cross holes and burrs on the inner surface that are difficult to remove by mechanical or manual methods. It can remove extra-hard mechanical parts such as molybdenum, nickel, Burr of titanium and quenched parts.
The deburring machine is an advanced deburring technology, and it is a new technology that develops rapidly and is widely used in electrochemical machining (electrochemical machining) technology. The deburring machine can achieve high edge uniformity and good surface quality for the processed edges. It has the advantages of good deburring effect, safety, high efficiency, energy saving and environmental protection. The deburring effect is good. In general, compared with traditional processes, the efficiency is Increase by more than 10-20 times. As a special application form of electrochemical machining, it has no mechanical force on the workpiece, and is easy to be automated or semi-automated. It is suitable for removing burrs from high-hardness and high-toughness metal parts and can be processed in a limited manner on specific parts of the workpiece. For complex internal cavity parts that are difficult to handle by hand and have poor accessibility, especially the burrs on the intersecting lines of cross holes, using a deburring machine has obvious advantages.
