Electro-Chemical Machining | Barber-Nichols
Electrochemical Machining (ECM) is a special process that rapidly removes material by anodic dissolution. BNI is one of the few companies in the world that make use of this process that is particularly suited to shape materials that are hard to machine with conventional methods.
Electrochemical machining - Wikipedia
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and ...
Electrochemical machining of complex …
Electrochemical machining (ECM) is a nontraditional machining process. As shown in Fig. 1, the workpiece is the anode, and the pre-shaped tool is the cathode.DC or pulse voltage (10–40 volts) is applied across the workpiece and tool.

ELECTROCHEMICAL MACHINING - idc-online.com
Electrochemical machining (ECM) is a metal-removal process based on the principle of reverse electroplating. In this process, particles travel from the anodic material (workpiece) toward the cathodic material (machining tool). A current of electrolyte fluid carries away the deplated material before it has a chance to reach the machining tool ...
Notes on Electro stone Machining (ECM)
Electrochemical machining (ECM) is a non-traditional machining process uses the principle of Faraday to remove metal from the workpiece. Electrolysis is based on Faraday laws of electrolysis which is stated as. weight of substance produced during electrolysis is proportional to current passing, length of time the process used and the equivalent weight of material which is deposited.

Information about electrochemical machining
Precise Electrochemical machining (ECM, PECM) is based on the ability of a metal to dissolve as a result of oxidic reactions occurring in the medium of the electrically conducting solution (electrolyte) under electric current influence. The dissolution process is called electrolysis. Specific features of the electrolysis process are the spatial oxidation (dissolution) of the anode and the ...
