Abstract

PURPOSE:To prevent a wire electrode from vibration attendant on the getting-over phenomenon of the electrode by a method wherein the drawing-out of the electrode from a wire electrode feed reel is always conducted substantially perpendicular to the rotary shaft of the feed reel. CONSTITUTION:When a wire electrode 10 drawn out from a wire electrode feed reel 12 contacts with wire electrode delivery position detecting means 54, 54 located between the reel 12 and the first pulley 14, a controlling means 52 based on the detection signal actuates a feed mechanism 40 consisting of a crank, rack-and- pinion and the like for position control of a rotary shaft 50 and the reel 12 in the axial direction of the shaft 50. Accordingly, the electrode 10 is always drawn out straight-forwards relative to the pulley 14, and it does not get over the electrode 10 wound inside on the reel 12, so that vibration can be prevented efficiently.
