Abstract

본 발명은 제트커터(Jet cutter)에 관한 것으로, 다양한 종류의 소재를 매우 효율적으로 가공할 수 있는 제트커터를 제공하는 것을 그 목적으로 하며, 작동유체를 공작물에 분사시키기 위한 노즐과, 작동유체를 저장하기 위한 작동유체탱크와, 상기 노즐과 작동유체탱크사이에 설치되어 작동유체탱크내의 작동유체를 고압상태로 노즐에 공급하는 펌프로 구성된 제트커터에 있어서, 상기 노즐로 부터 분사된는 작동유체를 고체상태로 상변화시키기 위하여 상기 펌프와 노즐사이에 설치되어 펌프로 부터 압송되는 고압의 작동유체를 과 냉각시키는 열교환기와, 내부에 상기 노즐과 공작물이 위치되며 대기압이하의 압력으로 유지되는 가공실로 구성되는 상변화수단이 구비된 것을 특징으로 함.The present invention relates to a jet cutter, and an object of the present invention is to provide a jet cutter capable of processing a variety of materials very efficiently, a nozzle for injecting a working fluid to the workpiece, and a working fluid A jet cutter comprising a working fluid tank for storing and a pump installed between the nozzle and the working fluid tank to supply the working fluid in the working fluid tank to the nozzle at a high pressure, wherein the working fluid injected from the nozzle is solid. It consists of a heat exchanger installed between the pump and the nozzle for phase change to a state to overcool the high-pressure working fluid pumped from the pump, and a processing chamber in which the nozzle and the workpiece are positioned and maintained at a pressure below atmospheric pressure. Characterized in that the phase change means is provided.
