PURPOSE:To miniaturize a wire-cut electrical discharge working machine to enable a large size workpiece to be fabricated, by providing a work feed device on a support bed which journals first and second arms so that the arms may be movable in two axial directions, independently from each other. CONSTITUTION:A wire electrode supply roller 34, a brake roller 37, a power feed roller 39, a capstan 41, a wire electrode recovery roller 42, etc. are provided on the first arm or working head 6 side, and an automatic wire electrode fold- back guide roller 43, etc. are provided on the second arm or working head 7 side. The first and second arms are journalled to a support bed 5, movably in two axial directions, respectively. The first and second arms are moved in the two axial directions, respectively, by means of an NC feed device, relative to workpiece 4. |
