Jet Electrochemical Machining (Jet-ECM), also called Electrolytic Jet Machining, is an unconventional procedure using localized anodic dissolution for micromachining. It is an innovative technology for the generation of micro geometries.

Jet-ECM is Electrochemical Machining with a closed electrolyte free jet. It is an innovative form of electrochemical removal, which applies high current densities connected with a high degree of local removal, a high localization of erosion and a high surface quality. The electrolytic current between the anodic work piece and the cathodic nozzle is supplied via an electrolyte jet which is ejected from a nozzle.

Jet Electrochemical Machining should not to be confused with Abrasive Jet Machining, Water Jet Machining or Abrasive Water Jet Machining, which are all mechanical processes.


Jet ECM in action The main advantage of Jet-ECM, as compared to other electrochemical processes, is that the electric current is restricted to a confined area by the jet which leads to a high localization of the removals. The removal amount and the machining position can easily be controlled by setting the electric current and the nozzle position. Even complex structures can be machined by the help of continuous direct current. Hence, higher local dissolution rates compared to pECM can be achieved.
