Waterjet Cutting in Newcastle

C&J Sheetmetal Fabrications utilize the latest Waterjet Cutting Technology. Our Omax Waterjet Machining Centres cut most materials up to 120mm.

Abrasive jets have been in use in the industry since 1982. Waterjets, the precursor to abrasive jets, have been in use since 1970. Abrasive jets are used in many industries, including the automobile, aerospace, and glass industries, to create precision parts from hard to cut materials. An abrasive jet uses water that is pressurized up to 55,000 pounds per square inch (3800 bar) and driven through a small sapphire orifice at 2500 feet per second (800 m/s), or about two and a half times the speed of sound. Garnet abrasive is then pulled into this high-speed stream of water in a long carbide mixing tube. A stream of abrasive-laden water moving at 1000 feet per second (300 Advantages of abrasive jets.

Abrasive jets hold a number of advantages over other machining methods:

  • Wide range of materials
    Abrasive waterjets can machine a wide range of thicknesses and materials, including metals, plastics, glass, and ceramics.
  • Quality finish
    Materials machined by the abrasive jet have a smooth, satin-like finish, similar to a fine sandblasted finish.
  • No heat in machining process
    Abrasive jets abrade material at room temperatures. As a result, there are no heat-affected areas or structural changes in materials with low melting points.

Environmentally friendly
Abrasive jets use garnet as an abrasive. Garnet is a reddish natural crystal, with a Mohs hardness of 6.5 to 7.5. No noxious gases or liquids are used in abrasive jet machining, nor are there any oils used in the machining process.

Minimal burr
No heavy burrs are produced by the abrasive jet process. Parts can usually be used directly without deburring.
