PCT No. PCT/JP86/00322 Sec. 371 Date Mar. 16, 1987 Sec. 102(e) Date Mar. 16, 1987 PCT Filed Jun. 24, 1986 PCT Pub. No. WO87/00102 PCT Pub. Date Jan. 15, 1987.A wire cut electric discharge machine having: a taper-machining table (6a) secured to the lower end of a vertical column (5a) disposed above a word table (T) capable of being moved in respective directions of an X-axis and a Y-axis perpendicularly intersecting each other in a horizontal plane and capable of being moved in respective directions of a U-axis and a V-axis perpendicularly intersecting each other in another horizontal plane parallel to the horizontal plane containing the X-axis and the Y-axis: a wire guide (7a) for guiding as wire electrode (9a), secured to the taper-machining table assembly (6a), and having a machining fluid spouting nozzle; and a cylinder member (24) fixed to arm (20), an elastic bag (28) contained in the cylindrical chamber (26) of the cylinder member (24), a plunger (30) vertically movably fitted in the cylindrical chamber (26), a roller (32) rotatably attached to the lower end of the plunger (30) and a branch pipe (34) which utilizes the pressure of a branch flow of the machining fluid supplied to the machining fluid spounting nozzle for applying a downward counterforce counteracting the reaction force of the spouting machining fluid to the taper-machining table assembly.
