PURPOSE:To stabilize the machining by a wire-cut electric discharge machining device, by providing a support members for resiliently or viscoelastically supporting guides for a wire-cut electrode so that a flexion and vibration which are produced in the wire electrode during machining are damped by the guide sections so that a trace produced on a wall surface of a machining groove is removed. CONSTITUTION:In a wire-cut machining device, machining liquid is fed into a gap between a wire electrode 1 moving between guides 3 and a workpiece 2 from a nozzle 6, and machining pulses are applied from a pulse power source 5 to repeat pulse electric discharge for electric discharge machining. Along the progress of the machining machining feed for a desired machining shape is applied to a machining bed 7 as to the two-dimensional X and Y axes of NC control while the workpiece 2 is fed relative to the wire electrode 1, and therefore, the workpiece 2 is machined while it is moved. A support member 8 for each wire guide 3 has a high damping characteristic for vibration to prevent the guide from vibrating. Although vibration of the wire electrode 1 due to electric discharge or the like is inevitable, the vibration may be damped by means of the support members 8, thereby it is possible to stably guide the wire electrode.
