Neutral salt solutions are commonly used in electrochemical machining of large metallic pieces *. In the present invention it is shown that a laser-jet, i.e., an electrolytic jet employing a neutral sodium chloride solution together with a collinearly directed laser beam through the same nozzle results in high-speed and high-resolution maskless electrochemical micromachining. In the present configuration very high current densities can be employed; hence, very high rates of metal removal can be achieved.
