Water jet cutting
Water jet cutting, a cold process, is actually nothing more than a highly accelerated form of erosion. Water has been working in on the earth's crust for millions of years. This is how the Grand Canyon originated for example. The grit carried along by the water is able to erode and wear the hardest of materials. This is no different to water jet cutting, with the big difference that the duration in which this takes place is made lot of shorter with the use of high pressure.
Water is forced through a small opening in the cutter head at a high pressure of 3500 bar to 6000 bar. Here the pressure of the water is converted into speed. With the added hard sand, the water leaves the cutter head at a speed of approximately twice the speed of sound. The impact energy on the material to be cut causes a cut of approx. 1 mm. Soft materials can often be cut with pure water.
- Cold processing.
- No thermal loads with as a consequence no structural changes to the material.
- Low mechanical load.
- No oxidation at the cut, no hardened cut edge, clean, practically burr-free cut.
- Extremely precise (approx. 0.1 mm to 10 mm thickness; approx. 0.2 to 20 mm thickness).
- Ideal cutting tool for practically all materials: Stainless steel, ordinary steel, titanium, aluminium, carbon, PEEK, laminated materials, glass, synthetics, rubbers, foams, fabrics, marble, granite, wood, paper, etc.
- Cut joints of 0.4 to 1.1 mm.
- No toxic gas production.
- Practically burr-free cuts.
- Material cutting losses are low.
- Time savings with the relatively high cutting speeds and multi-head cutting.
- Cut thicknesses to 400 mm.
- Environmentally friendly
