What is waterjet cutting?


The process of waterjet cutting involves using a small stream of water and abrasive to erode material along a predefined path to create shapes or parts. This technology allows us to cut very thick materials of almost any kind.

A pump pushes water up to 50,000 to 60,000 psi. The water is carried through very thick walled tubing to a nozzle on the machine. This is where the water is pushed through a tiny .014 inch diamond orifice creating the waterjet stream that exceeds speeds of 1,000 miles per hour. Just before the water exits the nozzle a small amount of abrasive (typically garnet rock) is introduced. The stream of water carries the abrasive out of the nozzle eroding almost anything in its way. The machine follows a programmed path turning the nozzle on and off where the material is cut into parts or designs. This process cuts without heat or material distortion making it perfect for anything from granite to titanium.
