The robot with 6 axes + external axis allows us to cut into 3d and get the correct cutting angle. Cut-off profile cutting and simple mantle of piping is performed with a clean and cold cut with great accuracy. It is possible to get cut with or without joints. Using the robotic studio and SolidWorks drawing software, one can carve out three-dimensional. For example, Cutting, Albu/pipe support, doubling discs, etc. Offline programming allows you to simulate what is to be cut. The method is based on cold cuts with a water pressure of 3-4000 bar. By means of a fokuseringsdyse, small amounts of abrasives are added to the water, making it possible to cut through soft and hard materials at a thickness of 1mm to 120 mm.
