Abstract
A wire-cut electrical discharge machine which effects an electrical discharges between a wire electrode and the workpiece. The wire-cut machine has a supply nozzle for supplying a machining fluid to an electrical discharge machining zone and a power-feed element for supplying pulse power to the wire electrode. The power-feed element contacting the wire electrode is provided inside the supply nozzle.
Claims6
A wire-cut electrical discharge machine which effects an electrical discharge machining of a workpiece by generating electrical discharges between a wire electrode continuously supplied from a wire supply unit and said workpiece, comprising:
- a nozzle means for supplying a machining fluid to an electrical discharge machining zone, said nozzle means being provided on the upper and/or lower sides of said workpiece;
- a power-feed element contacting said wire electrode in order to feed a current thereto, said power-feed element being provided inside said nozzle means;
- and
- a nozzle having a nozzle port for jetting out said machining fluid toward the electrical discharge machining zone, said nozzle being adapted to be vertically movable with respect to the power-feed element by means of the pressure of said machining fluid.
A wire-cut electrical discharge machine which effects an electrical discharge machining of a workpiece by generating electrical discharges between a wire electrode continuously supplied from a wire supply unit and said workpiece, comprising:
- a nozzle means for supplying a machining fluid to an electrical discharge machining zone, said nozzle means being provided on the upper and/or lower sides of said workpiece;
- a power feed element holder mounted within said nozzle means;
- a power-feed element adjustably mounted in said holder, said element contacting said wire electrode in order to feed a current thereto, said power-feed element being provided inside said nozzle means;
- an annular groove in said nozzle means;
- a nozzle port for jetting out machining fluid toward the electrical discharge machining zone, said nozzle port having a flange that fits within said annular groove;
- and
- a locking means for fixing the relative position of said nozzle port with respect to the nozzle means and the power-feed element, whereby when said locking means is unlocked, the nozzle port can be vertically moved with respect to the power-feed element by the pressure of said machining fluid.
