Abstract
A wire-cut electrical discharge machining apparatus having upper and lower tables which are disposed on a bed and movable in such directions as to intersect orthogonally with each other, and a wire electrode which is movably stretched so that a workpiece placed on the upper table can be machined by an electrical discharge produced between the electrode and the workpiece, and characterized in that a through hole is provided at least in the upper table, and upper and lower wire guides are provided above and below the through hole respectively, or inside the same, so that the wire electrode can be discharged via the lower wire guide.
