Abstract
To simultaneously machine a plurality of workpieces, 6, 6a a continuous wire electrode 2 supplied by a feed unit 1 is reversed by a pulley 21 below the movable mounting table 7 after passing down through one of the workpieces, and led back up through the other workpiece to a tensioning takeup unit 11. The wire electrode runs 2, 2a are maintained parallel by upper guides 3, 3a secured to a common mounting plate 20, and relative movement between the electrodes and workpieces is controlled to discharge machine identical configurations in both of them.
