ABSTRACT:
A wire-cut electric discharge machine which improves contact between a wire electrode and a conducting member without deforming the wire electrode to suppress production of minute electric discharges and reduce unnecessary loads on the wire electrode and the wire-cut electric discharge machine, and which makes it easy to make space on a wire traveling path to carry out automatic wire connection easily. In a wire-cut electric discharge machine having a conducting member for supplying an wire electrode with electric power for electric discharge machining, and making the wire electrode travel along a traveling path, sliding on the conducting member, a movable member capable of being moved nearer to and away from the conducting member is provided in a position opposite to the conducting member relative to the traveling path. By this arrangement, the contact between the wire electrode and the conducting member can be always kept without deforming the wire electrode.
