<p>A working fluid injection nozzle for a wire-cut electrical discharge machine comprises a first tubular member (15) which has a hollow portion through which an electrical discharge machining wire electrode extends in the axial direction thereof, and which is adapted to allow a working fluid to pass along the wire electrode; a soft tubular member (16) attached to the free end of the first tubular member (15); and a second tubular member (17) which supports the soft tubular member (16) by pressing it toward the center of the axis thereof, and is movable along the axis. The inner diameter of the soft tubular member (16) can be varied to provide adjustment by moving the second tubular member (17) along the axis thereof. </p> |
