How Electro-Chemical Machining Works

Machine tool builder EMAG has produced a very nice video that explains and illustrates how the electro-chemical machining (ECM) process is able to perform simple deburring operations as well as produce precision surfaces and shapes.


Electro-chemical machining (ECM) is a process by which metal is dissolved electrolytically as a means to remove burrs or create contours and other precision shapes. Machine tool builder EMAG, a company that also offers a line of ECM equipment, contrasts this process to “traditional” metalcutting processes. ECM produces no tool wear, no mechanical stresses, no heat, no surface oxidation and no other unwanted effects.
To show how ECM works and what it can do, EMAG has produced a video that presents ECM equipment in action, along with animations of the electrolysis taking place to remove burrs or create cavities and contours. It’s worth watching not only for its instructional value, but also as a reminder that thinking “non-traditionally” about machining processes may be the secret to successful solutions of difficult machining problems.
