<p>A wire electric spark machine provided with a wire electrode (2) which works a work (3) while causing discharge between a wire and the work (3) through a working fluid and an upper wire guide and a lower wire guide through which the wire electrode (2) is passed and which have a flow passage through which the working fluid flows, and further provided with a working fluid nozzle (147) which is fixed to a guide body section (133) and jets the working fluid toward the work (3), an electricity feeding die (162) which is incorporated in the nozzle (147) and electrically connected to the wire electrode (2), and a jetting means which is installed on the surface of the die (162), has a recess (162a) engaged with the electrode (2) in the direction of movement of the electrode (2), and presses the electrode (2) against the die (162) by jetting the working fluid toward the electrode (2).</p> |
