Principle of chemical deburring

Metal electrochemical machining technology, in the professional design of the fixture system, the workpiece and electrode are respectively connected with the positive and negative poles of the power supply. Under the action of electric field, flow field and working fluid, the charge exchange between the two stages is generated, which realizes the "ion removal" of the specific parts of the workpiece, and achieves the process requirements of deburring, rounding, polishing or forming.

Electrochemical deburring has obvious advantages for the complex cavity parts which are difficult to handle by hand and have poor accessibility, especially for the burr on the intersection line of cross holes. Electrochemical deburring can achieve high edge uniformity and good surface quality for machining edge, which has the advantages of good deburring effect, safety, high efficiency, energy saving and environmental protection, and good deburring effect. Generally, compared with traditional process, the efficiency can be increased by more than 10-20 times.

Automobile engine, general engineering machinery, aerospace, pneumatic hydraulic and many other industries are the most widely used and important equipment in electrochemical machining machine tools.

Machine features:

Suitable for internal burr which is difficult to remove;

It is suitable for finishing parts after heat treatment;

It is suitable for the whole field of metal cutting;

The use of non-linear electrolyte is harmless to human body.

Technical advantages

There is no electrode loss during machining. An infinite amount of products can be produced repeatedly with a single electrode;

There is no thermal stress on the workpiece after machining. Does not affect the existing properties of the artifact. There will be no micro cracks. Prolong the service life of the workpiece;

There is no oxide layer. The workpiece does not need to be processed later; The machined part has no mechanical stress. It can be used to machine structural parts with thin wall.

The surface quality of the electrode is reproducible. The roughness can reach ra0.05 μ m. Up to ra0.02 μ m； Precision machining can reach 1-10 μ m。
