– The use of very fast flow of abrasives in water with very high pressure (Psi 90,000 to 30,000 or Mpa 621 to 207) produced by the intensifier pump.
– Application for cutting a wide range of different materials including heat-sensitive materials, soft or very hard materials
– No thermal damage to the surface or edges of the work piece
– Nozzles are usually made of sintered boride.
– Creating a cutting angle (difference in the width of the gap at the top and bottom of the piece) less than one degree in most cuts, which can be completely eliminated by slowing down the cutting operation.
– The distance from the nozzle to the work piece affects the size of the gap and the cutting rate. This distance is usually chosen to be around 3,175 mm.
When heating materials are sensitive to cutting, it is preferable to use a water cutter.
Some waterjets use empty water (without abrasives) for cutting, which is suitable for cutting softer materials such as food, rubber and foam.
By changing the nozzle parts and the type and size of abrasives, the width or kerf of the cut can be changed. In normal cuts with abrasives, the cutting width is between 0.04 and 0.05 inches (1.016 to 1.27 mm), but it can reach a narrow 0.5088 mm.
In non-abrasive cutting, the cutting width is normally between 0.178 and 0.33 mm, but can be as small as 0.076 mm, which is approximately equal to the thickness of human hair. With these very small jets, very precise cuts can be made for a wide variety of applications.
