AUTOMATIC WIRE-SUPPLYING DEVICE FOR WIRE CUT ELECTRIC DISCHARGE MACHINING APPARATUS

摘要

An automatic wire-supplying device automatically feeds wire electrode (2) to a unit collecting the electrode (2) through a machining start hole (77) of a workpiece (38) from a wire supply reel (1), a cleaning unit for blowing fluid onto a wire guide (40) guiding the electrode (2) is provided, thereby blowing off contaminants such as machining swarf and maintaining the success rate of the automatic wire supply for a long period of time.
