Abstract
Disclosed is an electrochemical machining process for fabrication of cylindrical microprobes, which is effected by the tool acting as the cathode against the workpiece acting as the anode, taking advantage of a chemical reaction occurring between the workpiece and the tool, both being beneath the surface of an electrolyte, under such a controlled electric field that the workpiece can be machined to have a uniform diameter throughout its entire length. The electrochemical machining can be carried out with greater precision because a precise machining process because the volume to be additionally processed owing to the surface tension generated when the workpiece is dipped into the electrolyte is taken into consideration.
