Electro Chemical Machining

(1) Basic Principles

Based on the principle of anode dissolution during electrolysis and with the aid of a formed cathode, a process method is called electrolytic machining to shape the workpiece into a certain shape and size.

(2) Scope of use

Electrochemical machining has significant advantages for processing difficult-to-machine materials, complex-shaped or thin-walled parts. Electrochemical machining has been widely used, such as barrel rifling, blades, integral impellers, molds, special-shaped holes and special-shaped parts, chamfering and deburring. And in the processing of many parts, electrolytic machining technology has occupied an important and even irreplaceable position.

(3) Advantages

Wide processing range. Electrolytic machining can process almost all conductive materials, and is not limited by the mechanical and physical properties of the material such as strength, hardness, and toughness. The metallographic structure of the material basically does not change after processing. It is often used to process difficult-to-process materials such as cemented carbide, high-temperature alloy, hardened steel, and stainless steel.

(4) Limitations

The processing accuracy and processing stability are not high; the processing cost is high, and the smaller the batch, the higher the additional cost per piece.
