Capable of cutting a wide variety of materials using a very high-pressure jet of water and an abrasive substance. Waterjet cutting is often used during fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. Waterjet cutting is used in various industries, including mining and aerospace.
An important benefit of the water jet is the ability to cut material without interfering with its inherent structure, as there is no heat-affected zone (HAZ). Minimizing the effects of heat allows metals to be cut without harming or changing intrinsic properties.
Due to its relatively narrow kerf, waterjet cutting can reduce the amount of scrap material produced by allowing uncut parts to be nested more closely together than traditional cutting methods. Water jets also produce fewer airborne dust particles, smoke, fumes, and contaminants, reducing operator exposure to hazardous materials.
