Waterjet cutting is suitable for cutting metals that may be adversely affected by heat. This is particularly important in the aerospace and vehicle industries. Basically, waterjets can process greater metal thicknesses than lasers can, and they can cut more precisely than either plasma or flame jet procedures. This cold-cutting process is also ideal in the manufacture of miniaturised components, thanks to the fine or micro waterjet technology now available. The need for delicate, highly functional workpieces can be met by a positioning accuracy of 0.0025 mm, right down to the tolerance range of +/- 0.01 mm.
Advantages:
Material remains unchanged metallurgically
No heat-affected zones
No material distortion due to heat
No hardening of the material at the edge of the cut
No worrying smoke or vapours given off
Every alloy can be cut
