A waterjet cutting machine is unique in its ability to cut both metallic and non-metallic material with a completely cold cutting process. Unlike thermal cutting processes, the profiled material has no heat affected zone (HAZ) which can potentially cause issues such as reduced mechanical strength or corrosion resistance. A CNC waterjet cutter is also able to process extremely thick material while still giving an excellent edge quality with a minimum amount of taper. For some lighter materials pure waterjet is used, however for cutting metal an abrasive waterjet process is used with the introduction of a garnet material into the cutting jet.
