Zusammenfassung:PROBLEM TO BE SOLVED: To use a relatively thick pipe electrode, and to improve the accuracy of the side surface machining. SOLUTION: As a pipe electrode 14 rotated around the axial center by a rotating means, a material with a large thickness t0 is selected, and a cutting tool 24 is provided movable in the radial direction of the pipe electrode 14, immediately under a ring guide 21 to guide the pipe electrode 14 slidable. When the pipe electrode 14 is moved in the axial direction to a discharge machining position, the outer periphery of the pipe electrode 14 is cut off by the edge 24a of the cutting tool 24, and its thickness t1 is made thinner than the value subtracting the discharge gap δ from the maching allowance s of the side surface of a work 11 (t1
