Abstract
The dry electrical discharge machining is considered by the researchers as an environment friendly machining process and different specific aspects of this machining method are presented in the specialty literature. To obtain holes by electrical discharge machining, tubular rotating electrodes tools could be used. The paper presents a relatively simple device proposed to be used for applying the dry electrical discharge drilling. The rotation of the electrode tool could contribute to the diminishing of the errors of the circular shape in a cross section through the hole. Some preliminary experiments proved the possibilities to use this device to achieve holes in workpieces of low thickness. Test pieces made of stainless steel were machined by dry EDM and by common EDM. For the applied operating conditions, the dry electrical discharge drilling presents some advantages regarding the machined surface quality and the electrode tool wear, in comparison with the machining that uses liquid dielectric.
