Cutting - Waterjet cutting machines(1)

Waterjet cutting is the technology that makes possible to cut the largest thicknesses. The operation of the water jet is very simple. An external pump generates a water jet at a pressure of up to 6480 bar. The water jet is conveyed along a nozzle at the end of which there is a very small outlet orifice made of precious stones. The water jet that comes out, the size of a human hair, is already capable of cutting light metals. In this case, we are talking about a pure water jet. In order to considerably increase the cutting capacity, garnite sand is added to the water jet. The water and the sand come out at a supersonic speed, about four times higher than the sound's speed and the jet will be able to cut steel thicknesses up to more than 300 mm. In this second case, where granite sand is added to the water, we will talk about an abrasive water jet. The water jet systems are composed, therefore, of three fundamental elements: the pump and the pipes that make up the very high pressure water transfer system from the pump to the cutting head, the machine body along which the cutting head moves and on which the workpiece is positioned, and finally the control system that makes it possible for the human operator to program and control the processing phases.
