Electrochemical machining
(ECM)
The Principle of Electrochemistry
Electrochemical reaction is a chemical reaction that adjusted the electron energy on the surface of the electrode by electric potential to cause electron transfer between the electroactive substance and the electrode. The amount of electrochemical reaction can determine the processing efficiency in the electrochemical process according to Faraday’s law.
The Method of Electrochemical Process
The electrode, also called cutting tools, is used as the cathode, and the workpiece is the anode. The electrolyte and voltage are supplied between the cutting tool and workpiece to generate electric energy and chemical energy effects, and the redox reaction is obtained, thereby making the processing mechanism for metal material removal.
Application advantages of electrochemical machining
It can process all kinds of metals, no electrode wear, no stress left, no burrs, high reproducibility and high productivity.
