Wire-cut electrical discharge machining equipment
First Claim
1. 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 said upper table can be machined by an electrical discharge produced between said wire electrode and said workpiece, and characterized in that a through hole is provided at least in said upper table, and upper and lower wire guides are provided above and below said workpiece, said lower wire guide being positioned inside or below said through hole, so that said wire electrode can be discharged out of said apparatus via said lower wire guide.
