The principle of cutting through a thin stream of water sprayed under very high pressure on almost any material has several major advantages over other cutting technologies. The most important is universal use for a wide range of materials from paper and fabric to metal or even concrete. This is thanks to the possibility of adding a variable amount of abrasive (cutting powder) to the sprayed water stream. For soft materials, the water jet itself is free of abrasive and high speed of the cutting head, for metals and hard materials, more abrasive and cutting is needed at slower speeds. Another advantage is the so-called cold cut, ie there is no thermal deformation of the materials or the opal edge. It is also a very ecological method, as no harmful substances or wastes are produced, and used water and abrasives are used repeatedly. Waterjet cutting machines are manufactured in sizes from 1,2x1,2m up to 8x3m as standard in a three-sided design (ie xyz) functioning as a classic large-scale plotter. Some of them also have a rotating nozzle, which allows the cut to be chosen according to the chosen angle and can thus cut the conical shapes into the material.
