PROBLEM TO BE SOLVED: To provide a water-jet machining device which discharges machining water having abrasive grains mixed therein from a nozzle after stopping a machining work, to thereby prevent clogging of spray hole with the abrasive grain. SOLUTION: The water-jet machining device is formed of a workpiece holding mechanism for holding a workpiece, the nozzle for spraying water jet to the workpiece held by the workpiece holding mechanism, and a machining water feeding means for feeding high-pressure machining water having the abrasive grains mixed therein, to the nozzle. The water-jet machining device is comprised of a clean water feeding means for feeding clean water to the nozzle. COPYRIGHT: (C)2004,JPO |
