Aqua Jet uses powerful cutting force of water and sand (garnet) to create a unique cutting 'tool', or jet. Add this to a Numeric Control, with imaginative software and the accurate cold cutting of virtually any material is possible. The process is essentially the same as water erosion found in nature but greatly accelerated and concentrated. An important benefit of Aqua jetting is the ability to cut material without interfering with the material's inherent structure as there is no "Heat - affected Zones" or HAZ. Minimizing the effects of heat allows metals to be cut without harming or changing intrinsic properties.
