SOME CONSIDERATIONS CONCERNING THE ELECTROCHEMICAL DISCHARGE DRILLING

Abstract: One of the solutions used to increase the machining performances is to combine two or many different known machining processes; this is the case of the so-called hybrid processes. Nowadays, the electrochemical discharge drilling (included in the group of the hybrid machining methods) is used preferentially to achieve holes in workpieces made of insulating materials. Some aspects concerning the electrochemical discharge drilling method based on the using of the semidielectric fluid were studied in the laboratory for non-traditional technologies from the Technical University “Gh. Asachi” of Iaşi. A device adaptable on the workshop milling machine was built and experimented; the experimental results proved the possibilities to achieve holes of small diameter in workpieces made of difficult-to-machine metallic materials.
Key words: electrochemical discharge drilling, semidielectric work liquid, device, electrode tool wears.
