Electrochemical Machining (ECM) is a particularly suitable procedure for micro manufacturing. Main advantage compared to other procedures is the possibility to machine metallic work pieces without thermal or mechanical impact and the independence from the material's hardness. Jet Electrochemical Machining (Jet-ECM) is a new procedure for fast electrochemical milling of complex micro geometries. Based on the application of a closed electrolytic free jet, fast and localized anodic dissolution is realized [1]. Due to the extreme high electrolyte supply in the jet continuous direct current can be applied in Jet-ECM, which results in higher local dissolution rates compared to pulsed ECM processes. Actual feed rates of up to 300 mm/min can be achieved.
