Principle of Water Jet Processing A water jet is like a big version of a water gun, where ultra-high-pressure high-speed water, or a mixture of that water with abrasive particles, is used for processing. In general water jet systems used in industrial product manufacturing, tap water is filtered through a micron filter, and a dedicated high-pressure pump generates ultra-high-pressure high-speed water (with a speed of Mach 3 and a pressure of 3,200 kgf/cm²). This water stream is discharged from a water nozzle (made of diamond or sapphire) with a diameter of around 0.3 mm to perform cutting and other processing. When processing hard materials like metals, a mixing nozzle with a diameter of around 1 mm (such as binderless superalloys) is additionally attached, and processing is carried out using a water stream mixed with abrasive particles.
