Abstract: PURPOSE:To maintain the tension of wire to be delivered to an electric discharge machining section at a certain level by controlling the wire delivery mechanism of a wire-cut electric discharge machining unit so that, when the rolled-up amount of wire on a wire reel becomes small, the damping force will be reduced in response to the decreased amount of wire. CONSTITUTION:In a wire delivery mechanism 40, which is to send out an electrode wire 20 at a constant level of tension to the electrode discharge machining section of a wire-cut electric discharge machining unit, a mounting shaft 42 of a wire reel 22' is formed as a rotatable longitudinal axis, and also a damping device is provided to give the mounting shaft 42 a damping force which is gradually reduced in response to the reduced rolled-up amount of the electrode wire 20 on the wire reel 22'. The mounting shaft 42 is formed to be capable of engagement with and separation from a base shaft 48 in the direction of the up-and-down, but not capable of relative rotation in the rotating direction. Since the damping device, which consists of a press plate 62, a brake pad 64, and a second spring 66, functions to gradually reduce the damping force working on the mounting shaft 42 in response to the reduced rolled-up amount of wire on the wire reel 22', the tension of the wire 20 is maintained constant.
