Pure Water : Take tap water, pressutise it to 60,000 psi (4,000 bar) then force it through a very small hole, or orifice. This creates a tremendous amount of energy concentrated in a thin beam of water, travelling at close to the speed of sound. The result is an extremely powerful and a precise 'Pure Water' cutting tool.
Abrasive Cutting: An 'Abrasive' water system employs the same methods as 'Pure Water' however; the addition of an abrasive garnet mixed into the stream increases the cutting forces significantly. When the high-velocity water exits the orifice it creates a vacuum within the mixing chamber. The vacuum pulls abrasive from the abrasives line into the chamber where it is mixed with the water jet stream. The resulting mixture is then realigned in a focusing tube before exiting the cutting head nozzle. At this point the accelerated abrasive particles are now travelling at speeds fast enough to cut through the hardest of materials. all this is achieved by a water jet that is little more than 0.8mm in diameter.
What can we cut ?
With over 8 years of experience we have successfully profile cut a vast range of materials from low density foams to wear resistant steels.
