The principle at the root of a waterjet cut is simple but still surprising. As the name suggests, a jet of water is projected out of an opening at more than twice the speed of sound. The intense flow of pressure allows the water to cut practically any composite material and any kind of metallic alloy. The water flow is very fine, usually between 0.75 mm and 1.20 mm, which means the flow of water can cut details that are impossible to achieve with conventional cutting tools.
The addition of abrasive to the water jet means further types and thicknesses of workable composites and metals can be added. The reduced force of contact also eliminates the need for bulky tooling.
5 reasons why a waterjet cut is a great alternative to traditional cutting:
1. Universal cutting tool
The openings and focusing nozzles of the abrasive need to be replaced only if worn and does not depend on the material and thickness to be cut
2. Waste reduction
The waterjet technology’s strong points lie in the simplicity with which the waterjet can cut a wide range of materials, without worrying about the physical properties and understanding which tool is more effective for machining and removing shavings.
3. No heat damage
The waterjet generates a cold cut that does not alter the physical properties of the material, subsequently avoiding further processes.
4. Possibility of cutting complex shapes
The diameter of the waterjet is so small that it easily permits the cutting of shapes of any size, even those with very narrow internal profiles and radii.
5. No more complex or bulky tooling
Due to the absence of friction, the piece blocking during processing occurs more neatly and with fewer complications.
