CNC Waterjet cutting centres – The water’s energy
This is the cutting technology that is quickly emerging in all major sectors, particularly in aeronautics. It has the huge advantage to allow the cutting, while avoiding at the same time any thermal and mechanical stress on the material, with evident advantages in terms of stability of physical properties. It is a concentrated, extremely powerful jet of water that, thanks to the latest technology, can reach an unbelievable pressure, more than 6,000 bar! The water pressure is generated by a pump with an intensifier, and inserted in the supply circuit to get to the cutting head, which is equipped with a diamond nozzle with a very small calibrated hole. The water is accelerated up to 3 times the speed of sound and the energy so trapped by the water molecules, it becomes an extraordinary cutting tool, suitable for any material. At the jet with pure water, an abrasive can be added in order to amplify the power, and considerably increasing the cutting efficiency. It is thus possible to cut extremely hard materials, such as stainless steel and marble with relatively important thickness.
