Water-Jet Cutting

In 2003, we have induced water jet cutting machine from Dardi international corporation. For Stainless steel plate which is thicker than 25 mm, we will apply water jet cutting. We provide customized service. We not only cut stainless steel material but also receive customers’ design with different format.

  • A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very highpressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite, while the terms pure waterjet refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.

    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, for cutting, shaping, and reaming.

  • Machine Type Waterjet
    Function Waterjet Shape Cutting for All Alloys including: Aluminum, Stainless, Titanium,Nickel, Carbon,
    Alloy, Brass, Copper as well as non metal materials. Cuts near net shapeswith no heat-affected zone.
    Basic Limits Width 120”
    Length 144”
    Maximum Thickness6”
    Minimum Diameter 1”
    Maximum Diameter 119”
    Standard Tolerance: Tolerance for this type of machinery is based on the
    speed that the machineryis run at and the thickness of the
    material being cut. The slower the speed, the tighter the tolerance.
    The following shows estimated tolerance.1/2” and Below 20% Speed - +.010” - .0”
    100% Speed - +.020” - .0”
    Over ½” to 1” 20% Speed - +.014 - .0”
    100% Speed - +.030” - .0”
    Over 1” to 2” 20% Speed - +.020” - .0”
    100% Speed - +.060” - .0”
    Over 2” 20% Speed - +.030” - .0”
    100% Speed - + .100” - .0”
  • Dynamic Waterjet® machines are an excellent choice for cutting stainless steel plate and sheet due to the fact that they use a cold cutting process and put very minimal pressure on the cutting material. Still, before selecting this method, it is important to consider many factors, including cost, tolerance requirements, material size and thickness, desired edge quality, lead time, and also any additional processing that will occur after the cutting step.

    Benefits of Dynamic Waterjet Technology when cutting stainless steel plate include:

    •No heat affected zone.

    •Very unlikely to cause warping or other distortions, as compared to other cutting processes.

    •Extremely versatile process, enables very detailed 2D/2.5D geometry.

    •Environmental friendly process. No harmful substances.

    •Taper and stream lag are very minimal, virtually eliminating the need for secondary processing.

    •Thin cutting stream, resulting in narrow kerf

    •Dynamic waterjet enables tight part-to-part separation for nested parts

    •Low cutting forces (under 1 lb. when cutting)

    •If secondary processing or milling is required for extremely tight tolerances, there is no hardened edge to grind off.

    •Can be used to cut all stainless steel grades.

    •Particularly beneficial for heat sensitive grades, such as 17-4, 410, 420, and 440, because laser or plasma cutting may cause these materials to harden at the heat-affected zone.

  • When choose the water-jet cutting

    •Costs.

    Waterjet cutting is a very ideal process. In comparison to the laser cutting, waterjet cutting costs are typically more expensive. However, when material thickness is over 20mm, the cost of water jet cutting is similar with laser cutting and plama cutting.

    •Material Costs. It is important to consider the cost for all material used, including the skeleton that is left behind after the cut. The skeleton weight is fairly minimal in the case of waterjet cutting, even for thicker parts. There will be less material loss in the process.

    •Costs of additional processing requirements.

    There is less or no additional additional steps after apply water jet.
