<p>PURPOSE: A water-jet cutting apparatus capable of easily changing a nozzle is provided to maintain stable array state of a flow path although a nozzle is expanded and deformed by high pressure water. CONSTITUTION: A water-jet cutting apparatus(100) capable of easily changing a nozzle comprises a nozzle holder(110), a nozzle(130), and a nozzle fixing unit(120). The nozzle holder has an inner flow path(111) and a nozzle insertion part(113). A part of the nozzle body is inserted into the nozzle insertion part and is detachably mounted. The projection of the nozzle is formed along the circumference of the nozzle body. The nozzle fixing unit has an exposure aperture(123) on one end thereof. The nozzle fixing unit pressurizes the projection and is detachably coupled with the nozzle holder.</p> |
