ABSTRACT:
A pulsating current comprising only positive half-waves separated by zero-current intervals is fed into an electrolyte between two electrodes in which the cathode is constituted by a tool and the anode is constituted by a part to be machined in accordance with the profile of the cathode. The electrolyte is of the passivating type which preferably contains between 30 and 50 grams per liter of sodium nitrate.
