Waterjet cutting machine FAQ
time2011/11/03
Q: What kinds of materials can waterjets cut?
A: Waterjets can cut a wide variety of non-metallic materials such as paper, foam, rubber, plastic, cardboard, paper, fiberglass and non-wovens. Abrasive waterjets (abrasivejets) can cut hard and thick materials such as stainless steel, aluminum, brass, steel, nickel alloys, marble, granite, glass, tiles, composites and ceramics.
Q: What tolerances can we expect from waterjet cutting?
A:Cut parts are within 0.051mm (.002")~0.254 mm (.010") accurate. The accuracy you get will depend on the accuracy of the machine, part size and part thickness.
Q:What is the kerf width for waterjet?
A:The kerf width depends on the thickness of the material being cut and the size of the orifice used. Generally the kerf for pure waterjet is between 0.1mm and 1.1mm, and the kerf for abrasive waterjet between 0.8mm and 1.8mm. The kerf will get larger as the mixing tube wears.
Q: What taper can I expect?
A: The taper you get is a function of the cut speed. The worst taper you will get will be equal to maximum kerf width at the top (example: 0.44mm) and 0.0mm at the bottom. As you slow down the taper will be reduced until you get parallel sides. Most tapers you see on good quality cuts are 0.076mm~0.102mm on a side.
Q:What kinds of material should be cut by waterjet?
A:Waterjets are especially suitable for cutting thick, hard, brittle, or heat-sensitive materials.
Q: What does a waterjet standard package include?
A: Generally a waterjet cutting system includes an ultrahigh-pressure pump, one to two waterjet cutting heads, an X-Y waterjet cutting table, CNC or PC controller and the associated CAD/CAM software.
