The problem of metal burr removal in machining has been a major concern at home and abroad for many years. How to use the principle of electrochemical deburring to solve practical problems in the production process is especially necessary. With the development of society and the continuous improvement of mechanization technology level, there is an urgent need for a machine with good performance and high degree of automation. Instead of the traditional manual deburring method. Electrochemical deburring systems can meet this demand when the final process of industrial production (ie deburring) requires advanced, precise components. Designing a suitable deburring program with high efficiency and complete automation (a viable manufacturing system) is a difficult problem. Because the shape, size, and properties of the burrs are ever-changing, there is no standard at all, which forms the current artificial deburring idea. In particular, the removal of burrs in the inner and intersecting holes is quite difficult. It can be said that electrochemical deburring is a promising solution to the problem. Therefore, it is necessary to develop electrochemical deburring. In this study, the electrochemical deburring mechanism using the electrolyte was introduced, and the results of the burr removal in the inner hole and the intersecting hole were described. At the same time, the deburring efficiency and effect of the device were studied under different electrolyte flow rates and other electrochemical conditions. A suitable deburring method has been established for the inner bore of the cylinder earring valve body and the intersecting holes (given workpieces).

The electrochemical deburring machine developed by Suzhou Rate Electromechanical Technology Co., Ltd. uses electric energy and chemical energy to dissolve the anode to remove burrs. The mechanical part is connected to the anode of the DC power source as an anode, and the forming tool is connected to the cathode of the DC power source as a cathode, and a certain gap is maintained between the two poles to allow the electrolyte to circulate. When the anode and the cathode are immersed in the solution and a direct current is applied, an electrochemical reaction occurs on the surface of the anode, and the surface of the mechanical part is dissolved by the metal and the electrolyte forms a viscous liquid concentrated in the concave surface of the surface of the mechanical part, having a higher electrical resistance and Small corrosion; while the burr protrudes from the surface of the mechanical part, under the influence of the temperature difference, the liquid film is difficult to form. After the power is applied, the power line is highly concentrated on the burr. The burr closest to the cathode will dissolve at the fastest speed until the burr is completely dissolved and the edge gradually The rounded corners are formed to achieve the purpose of deburring.

Electrochemical deburring machine tools for the industry:

Automobile engines, general engineering machinery, aerospace, pneumatic and hydraulic industries are the most important equipments for the production of electrochemical machining machines with a large number of applications and the widest application fields.

Electrochemical deburring machine features:

1. Suitable for internal burrs, heat treatment and finished parts that are difficult to remove.

2. Small rounded corners can be formed at the intersections or edges of the holes.

3. Do not damage the finished surface.

4. The efficiency of deburring is high, and each processing cycle takes only 2~3 minutes.

5. Multiple pieces can be removed at the same time
