PURPOSE:To make it possible to facilitate and smoothen automatic coupling of wire electrodes, by deburring the forward end of a wire electrode having been cut by a wire electrode automatically cutting means such as a cutter, a shear or the like with the use of electrical discharge. CONSTITUTION:After completion of an electrical discharge machining process, a cutter 4 is operated to cut an wire electrode 2. At this time burrs are pro duced on the cut end face of the wire electrode 2, causing the operation of a wire electrode automatically feeding means 5 to be hindered, and therefore, these burrs should be removed. After the wire 2 being cut, the cutter 4 is shifted to be opposed to a part 31 which is to be cut off as an end element for a work piece 3, and then electric discharge is effected. The forward end of the wire electrode 2 having been deburred is smoothly connected through the above- mentioned means 5.
