WATERJETS HAVE A NUMBER OF ADVANTAGES OVER OTHER MACHINING METHODS:
Wide range of materials:
Abrasive waterjets can machine a wide range of materials including metals, plastics, glass, wood, rubber, ceramics and have an advantage over lasers in that they can handle reflective materials such as aluminum, brass and copper.
Parts can be made from sheets of material as thin as .001" to plate material 3" thick.
Materials cut by the waterjet have a smooth, satin-like finish similar to a fine sandblasted finish.
No heat involved:
Waterjets cut the material under water at room temperature. As a result there are no heat affected areas or structural changes to the material or parts. Waterjets can also machine hardened metals and materials with low melting points.
No tool changing:
A wide range of conventional processes can be performed with this single tool:
-Broaching -Gear cutting
-Profile milling -Slitting
Depending on the thickness of the material being machined, tolerances as close as + -.002” can be held.
No heavy burrs are produced by the waterjet process.
