Kondisi: baru, x-travel: 3000 mm, y-travel: 2000 mm, z-travel: 250 mm Pump capacity for flushing: 37 kW Control: Siemens PLC Touch Screen, directly usable DXF files Output pressure: max. 5500 bar Abrasive feed system for waterjet cutting machines - Fill weight 350 kg OMAX vacuum sensor for monitoring abrasive feed to the nozzle Sensor for monitoring pump pressure In waterjet cutting, water is compressed to a pressure of up to 5500 bar. Depending on requirements and workpiece, the water is then forced through a nozzle with a diameter of 0.01 to 0.08 mm. Since waterjet technology processes materials without heat input, deformations are avoided. By adding an abrasive, waterjet cutting achieves the highest precision with tolerances of +/- 0.01 mm. Our flexible production allows for both vertical and beveled cuts. We are happy to work with your individual CAD data. Waterjet technology offers significant advantages for industry, crafts, and prototyping. It is also environmentally friendly, as the process produces neither dust nor vapor and is very material-efficient. Waterjet Cutting: Sample Gallery What sounds impressive in theory is even more striking in reality. We have compiled a selection of images to demonstrate our waterjet cutting capabilities. Click through our gallery to see what is possible with this modern machining process. Waterjet will find the optimal solution for your project!
