Technology and capabilities

A waterjet is a cutting-edge industry tool capable of slicing different materials using a jet of water at ultra high velocity (762 meters per second, or about x2.5 the speed of sound) and pressure (up to 60,000 PSI). A mixture of an abrasive substance, such as garnet, is added to the water to create an abrasive waterjet that can cleanly cut through any hard surface. Waterjet cutters are not typically limited by the thickness of the material, and are capable of cutting materials over twelve inches (300mm) thick.

A waterjet cutting headAn important benefit of the waterjet cutter is the ability to cut material without interfering with the material's inherent structure as there is no "heat affected zone". Minimizing the effects of heat allows metals to be cut without harming or changing intrinsic properties. They are also capable of producing rather intricate cuts in material. The width of the cut (Kerf), can be changed by changing parts in the nozzle, as well as the type and size of the abrasive material.

Waterjets are environmentally friendly and produce no hazardous waste. They can cut off large pieces of reusable scrap material that might have been lost using traditional cutting methods, parts can be closely nested to maximize material use, and the waterjet saves material by creating very little kerf. Waterjets use very little water (a half gallon to approximately one gallon per minute depending on cutting head orifice size), and the water that is used can be recycled using a closed-looped system.
Waste water usually is clean enough to filter and dispose of down a drain. The garnet abrasive is a non-toxic natural substance that can be recycled for repeated use.

The waterjet can help us achieve many different goals, for example:
  • Slice almost any material, even very thick ones, at a minimum kerf of 0.6mm, which gives us endless possibilities.
  • Cut holes at a minimum of 1.5mm, which can be used to cut out jammed tools as stuck drill heads, without damaging the part.
  • You can create a part with very close messurements and do the finish with a milling machine, thus saving time and money.
  • It can cut materials which can't be cut with plasma or laser, like thick laminated glass & stainless steel etc.
  • Make your own specialist tool, to fit your exact needs, making your work more efficient and time saving.
  • The ability to cut curves makes it perfect for cutting logos and designs.
  • Easily creating Inlay decorations out of marble or glasses.
  • Very useful for creating signs and cutting letters from many different types of fonts at all sizes.
  • Build architectural models & production prototypes, in exact messurements, from any material you choose.
