This paper presents an experimental study related to the production of microholes with use of the ECDM-technology (electro chemical discharge machining), applying here adequate conditions of experiments to analyze the work result after the machining process (machining time, external diameter of holes and tool-electrode wear). These produced holes have diameters smaller as 200 m, according to the adjusting of ECDM-parameters as well as of the dimensional characteristics of the tool-electrode. Fundamentally, in the experimental investigations of this article, the influence of the ECDM-prozess parameters (chemical composition of the electrolyte solution, electrolyte conductivity, rotational velocity of tool-electrode and total energy of the electric discharge adjusted through a capacitance of the electrical generator of the tool-machining) was verified on the above mentioned output variables of the ECDM-machining, where in this case stainless steel has been applied as workpiece material to be machined. The experiments' results indicate a strong effect of these input-variables on the work result as consequence of profound alterations of the characteristics of material removal of the machining process. This removal substantially depends of the energetic content of the phases EDM (electrical discharge machining) and ECM (electrochemical machining) of the ECDM-technology, dependently on the correspondent adjusting level of an input-variable to machine a microhole.
