What is the waterjets principle?

The inlet water is pressurized between 20,000 and 60,000 Per Squire Inch (PSI) by intensifier pump. This is forced through a tiny hole [typically called “orifice” or “jewel”, which is typically 0.18 to 0.4 mm in diameter].This creates a very high-velocity and very thin beam of water traveling as close to the speed of sound, with an extreme amount of energy in a point, which can cut some soft materials. As the thin stream of water leaves jewel, abrasive is added to the stream and mixed. The high-velocity water exiting the jewel creates a vacuum which pulls abrasive from the abrasive line, which then mixes with the water in the mixing tube. The beam of water accelerates the abrasive particles to speed fast enough to cut through much harder materials.

What are the advantages of waterjet machine?

1. Can work with a wide variety of materials, including brittle materials2.Almost no heat generated on your part

Only when pierce 5cm thick steel, temperatures may get as high as 50°C, but otherwise machine is done at room temperature.3.Can machine thick materials

It is common to machine up to 10cm for steel4. Narrow kerf removes only a small amount of material

The amount of material removed by waterjet stream is typically about 0.5mm wide, meaning that very little material is removed. When you are working with expensive material, this can be a significant benefit.5.Lateral forces are negligible which means holes can be placed very close to the material edge 6.The edge finish created with a waterjet is smooth7.Morden systems are now very easy to learn and operate8.Fast setup and programming9.Little fixturing for most parts 10.Are very safe11.Environmentally friendly
