Waterjet Cutting Comparison With Other Methods

Waterjets can cut any solid material including stone, tile, glass, metal, foam, rubber, plastic, and food. When compared with plasma, laser, and edm – waterjet cutting has distinct advantages.

As the grid above illustrates – and the image to the right shows, waterjet cutting technology has clear advantages over other cutting methods.

Green Benefits
Waterjet cutting is a cold-cutting process that eliminates slag deformation and dross waste – unfortunate effects found in plasma and laser cutting processes.

Additionally, both the garnet used in abrasive cutting as well as the water are recycable.
