International marketing corporation provides various water jet cutting systems from water jet, sweden. The technology behind this water jet cutting tools is unique, advanced way to augment the level of automation since it will cut almost all materials cost effectively. Material separation energy is obtained by focusing high pressure, high speed water through a fine precious stone orifice. The heart of 2d or 3d cutting systems is the high-pressure pump - a streamline intensifier pump with hydraulic drive from ingersoll-rand. In the primary circuit, hydraulic oil is pre-pressurised using a hydraulic pump. This pressure is then multiplied using the intensifier in the secondary circuit. In continuous operation, the high pressure pump can work at up to 3800 bar with a jet stream velocity of 800 m/s [equals 2.5 times the velocity of sound] exiting from the focusing nozzle in the cutting head. The potential energy is converted into kinetic energy in this way. The cutting water is filtered before hand in order to protect the high pressure parts and the intensifier. The abrasive cutting head with inserted focusing nozzle is integrated into the manipulator which can either be a root, 2d or 3d gantry. The system can also be integrated into a slitter where the material is moving under the jet. In 3d cutting, the part is lightly fixed on to a grid and the manipulator moves the head along the pre-programmed path. Features includes that with pure water and no additives, cutting of textiles, elastomers, non wovens, thin plastics, etc. Can be possible, with speeds of well in excess of several hundred metres/minute depending upon the material. Abrasive jet cutting are used in order to separate harder materials such as metals, stone bullet proof glass, ceramics, etc.
