The paper presents some theoretical considerations and experimental results concerning the electrode tool wear at the electrochemical discharge drilling of spring steel. It is known that the electrochemical discharge machining is a hybrid machining method, in which the workpiece material is removed as consequence of some electrochemical dissolution and electrical discharge processes. When the electrolyte used as work liquid generates insulating layer on the workpiece surface, a relative motion and pressure are necessary between the electrode tool and the workpiece. Taking into consideration such requirements, a relatively simple equipment was designed and built to ensure the conditions necessary to develop the electrochemical discharge drilling. The influence exerted by the diameter of the electrode tool, the voltage applied to the electrode, the capacitance of the electrical circuit and the density of the work liquid on the axial wear of the electrode tool was studied.
