ELECTROCHEMICAL MACHINING AND ELECTROCHEMICAL DEBURRING

Electrochemical machining (ECM) is essentially a reverse metal-plating process (Figure M-112). The process takes place in a conducting fluid or electrolyte pumped under pressure between electrode and workpiece. As workpiece material is deplated, it is flushed away by the flow of electrolyte.
Workpiece material is removed from the electrolyte by a filtration system.

Advantages and Applications of ECM Like EDM, ECM can accomplish machining of intricate shapes in hard-to-machine material. The process is also burr-free and does not subject the workpiece to distortion and stress, as do conventional machining processes. This makes it useful for work on thin or fragile workpieces. ECM is also used for part deburring in the process called electrochemical deburring
(ECDB).
This process is useful for deburring internal workpiece features inaccessible to traditional mechanical deburring processing.
