Waterjet Cutting
Waterjet cutting is an accelerated erosion process within a selected material. Highly pressurised water is fired through a ruby or diamond nozzle into a mixing chamber. This pressure creates a vacuum and draws garnet sand into the stream where it is then fired at the object in place for cutting. The sand particles eat away at the material causing the effect of erosion to take place at such a high speed it is deemed as cutting.
