Because composites are not homogenous materials and are reinforced for greater strength, cutting composites are always considered to be a tough work. As a non-contact cold cutting process, waterjet does not produce heat-affected zones, or leave rough edges and burrs. High pressure waterjet can cut the composites in a fast speed. The abrasives added in the cutting also have grinding function which will make the cutting surface smoother, cleaner and more accurate. Therefore, waterjet is the best choice for composite cutting.
Abrasive water jet cutting is more popular, especially when it comes to metal cutting such as steel, stainless steel, tool steel, aluminum, brass, copper, titanium, nickel, alloys and any other special metals. Abrasive water jet cutting is used for glass cutting and stone and tile cutting, but it is different from steel cutting due to its brittleness and vulnerability. All of these applications are used in the automotive industry, the aerospace industry, the yachting and marine industry, and military defenses.
