Abstract

PURPOSE:To aim at making it possible to carry out electrical discharge machining for precise machined diameter and curve, by using a flexible electrode which is obtained such that an electrical discharge wire electrode is disposed, as a core wire, in a metal pipe together with insulator power filled between the gap therebetween, and the diameter of the thus composed metal tube is reduced with the use of dies, rolls or the like. CONSTITUTION:In order to give press-binding of high-insulation powder and flexibility to an electrode, an electrode wire 1 is disposed in a metal pipe 2 having more than 10mm. diameter and less than 3.0mm. wall thickness, which is easily plastic-deformable, with an insulator 3 being filled the gap between the pipe and the core electrical wire to obtain a starting material. Then the material as a whole including the outer shell pipe proper is subjected to plastic-deforming machining with the use of dies, rollers 5 or the like, so that the outer diameter of the material is more and more reduced down to a fine diameter, thereby the electrode wire 1 in the pipe comes to have a fine diameter. Thus, the thinned material may be formed as a finely thin pipe having less than 0.2mm. outer diameter and provided with a flexibility, and as well, the electrode wire therein may have a fine diameter. Further, the material may be connected to a ring pipe section 4 as an electrode holder.
