Electrochemical Deburring Machine

Electrochemical deburring is an advanced deburring process. The basic principle is that, according to the "tip discharge" effect, when the workpiece is in a special environment with a strong electric field (this strong electric field is formed by strengthening a large current outside a specific solution), the protruding part of the edge immediately gathers a strong current and generates a "tip discharge", and then, an electric spark is generated, so that the tip of the workpiece edge becomes a smooth arc, and the processing residue is completely removed to make the wall smooth. According to the electric field theory, it is known that the burrs and other protruding parts on the surface of the part are more concentrated in charge, while the surface depressions have less charge. Due to the uneven distribution of power lines, the distribution of power lines in the protruding parts is dense, the current density is high, and more metals are removed (see graph); the distribution of power lines in the concave parts is relatively sparse, the current density is lower, and the less metals are removed. Since the current density passing through the burr is much high than other parts of the anode surface of the workpiece, the burr is quickly dissolved.
In addition, through the rational use of tool masking technology, burrs can be selectively removed without affecting the original dimensional accuracy and surface quality of the anode surface of the workpiece.
It has high efficiency, fast speed and stable quality;
Since the gap effect of pulse current and the stirring effect of pressure wave improve the electric field and flow field conditions in the processing gap, and reduce the requirements for the flow characteristics of the electrolyte, it is conducive to obtaining a stable and ideal process;
It will not cause any damage to the physical and chemical properties of the processed parts, and there is no obvious damage to the processed dimensions;
Since there is no cutting force during the processing, no additional stress or surface modification layer will be formed, and the micro-geometry of the processed surface and the physical, chemical and mechanical properties of the parts can be improved;
It can be used where mechanical methods cannot be achieved and is widely used.
