Outside corner radii of 0.025 mm are possible, although inner corner radii are limited to 0.25–0.4 mm due to "overcut" during electrochemical reaction. Accuracies are typically ±0.025 mm on a one-pass cut, but ±0.005 mm can be achieved on the final pass without the use of electrolyte. See Also: Electrochemical machining and Grinding

Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
