Water is pressed through a nozzle with a pressure of 4,000–6,000 bar
and a bundled waterjet is discharged with twice the speed of sound (Mach).
This technology is used for precision work and fine cut. No more warping of mounting plates, ecologically safe and clean. Precision cut up to 2 microns.
Water is pressed through a nozzle with a pressure of 4,000–6,000 bar and a bundled waterjet is discharged with twice the speed of sound (Mach).
To increase the kinetic energy, abrasive (granite sand) is added after the water nozzle to cut harder materials. The waterjet accelerates the abrasive sand grains to approx. Mach 2. This sand-water mixture cuts through any material with a hardness of up to approx. 8 on the Mohs scale. The work piece stays cold for the most part because the cut is cooled off immediately by the water. Waterjet cutting does not cause any structural changes, increased hardness or harmful gases.
If abrasive (granite sand) is added to the waterjet after the water nozzle, hard materials like glass, metal, , composite materials and the like with a thickness of up to 300mm can be cut. Generally, it can be said that materials with a hardness up to that of the abrasive (approx. 8 on the Mohs scale) can be cut with the abrasive-waterjet.
The faster a material is cut with waterjet, the coarser the cut will be. In principle it must be said that doubling the material thickness generally cuts the feed value by more than half the value.
