摘要：
A wire electrical discharge machine includes a wire electrode for causing electrical discharge to take place between the wire electrode and a workpiece; a first roller and a second roller for feeding the wire electrode while nipping the wire electrode; wire conveyor for inserting the wire electrode into a portion between the first roller and the second roller by causing a fluid to flow to opposing portions of the first roller and the second roller; and driver for moving a distal end of the wire conveyor to a vicinity of the opposing portions, and for moving the distal end of the wire conveyor away from the opposing portions a predetermined distance upon completion of the insertion of the wire electrode into the nip between the first roller and the second roller.
