Cut Quiet. Cut Clean. Cut Under Water.
There's a common misconception that waterjets are noisy and dirty machines. While it's true that cutting above water can be noisy and throw a lot of abrasive dust into the air, modern abrasive waterjets let you cut under a thin layer of water, reducing the noise level to below that of most machine tools and keeping the abrasive particles in the water, not in the air. A waterjet cutting under water can be placed anywhere that you'd place a conventional machine tool. One more benefit of cutting under water is that it helps prevent frosting on the surface finish. If the standoff distance between the mixing tube and the work material is relatively large, "frosting" or "hazing" can occur on the top edge of an abrasive waterjet cut. Cutting under water reduces surface frosting that may occur.
