Depending on the requirements and the workpiece, this is then pressed through a nozzle with a diameter of 0.01 to 0.08 mm. Since water jet technology processes materials without heat input, there are no deformations. By adding an abrasive, water jet cutting enables maximum precision with tolerances of +/- 0.01 mm. Our flexible production allows vertical as well as diagonal cuts. We would be happy to receive your individual CAD data. The water jet technology offers great advantages for industry, trade and individual prototype production. Water cutting technology is also a plus point for the environment, as it works dust- and steam-free and also saves material. Waterjet Cutting: Example Gallery What sounds impressive in theory is even more impressive on the finished object. We have put together a selection of images to demonstrate our waterjet cutting capabilities. Click through the photos in the example gallery and get an impression of what is possible with this modern processing method. Waterjet will also find the right solution for your order! benefits No deformations in the cutting area Cutting without heat input Material saving High precision: +/- 0.1mm Cutting area: x = 3010 mm; y = 2010mm; Z=250mm Flexible manufacturing Vertical and oblique cuts Adoption of your CAD data formats: DXF, DWG, iges, stp, step, prt, jpt, jam Environmentally friendly, vapor and dust free We cut everything All materials brought into shape aluminum steel Brass Copper & Bronze Other precious metals Glass Granite & Marble tiles composites Promat cuts rubber plastics plexiglass Options: Oil cooler                                                         ¤ 10,725.00 Dksdpod Ab Uuofx Am Rsn Water filter system                                           ¤   1,430.00 Sludge suction system                                     ¤ 10,725.00 Professional water treatment system               ¤ 10,725.00 An oil cooler must be present when commissioning!!!
