When water jet cutting, a jet of water strikes a surface at high pressure, where it causes the desired material removal through the removal of material. The most important factors influencing the cutting performance are the water pressure, the diameter of the nozzle and the nozzle distance to the material. The more pressure, the higher the cutting depth and cutting performance.
In addition to high-pressure pumps, nozzles with a diameter of 0.1 to 0.5 millimeters and a water pressure of up to 3,000 bar are used to produce the fine water jet. When cutting moves a feed device the water jet at the desired distance and at a certain speed along the cutting line. On the know-how pages of URACA you can find out more about waterjet cutting.
