摘要： 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.

摘要： A current pickup assembly for placing electrical current on a moving wire electrode (12) in an electrical discharge machine apparatus and having a normal straight line of travel. The current pickup assembly includes a current pickup (36) having a bore (38) therethrough for receiving the wire electrode (12). The bore longitudinal axis (R) is at an angle (α) with respect to the normal straight line of wire travel and the moving wire electrode (12) contacts the bore contact wall (40) therein. A pivot means is provided for selectively pivoting the carbide pickup longitudinal axis (R) at an angle (α) with respect to the straight line of wire travel. A rotation means rotates the current pickup (36) about the bore longitudinal axis (R). In the alternative, the current pickup is supported on a gimball means for selectively pivoting the pickup about two mutually perpendicular and intersecting axes of rotation (X, Y) intersecting at a point (42). A control shaft (46) connected to the current pickup (36) and engaged with a connecting rod (54) are driven by a drive means (m) through a variable displacement means. Thus, selective angular displacement of the bore longitudinal axis from the normal straight line of wire travel and also rotational movement of the bore longitudinal axis about the normal straight line of wire travel are provided.
