Almost anything: From plastic to bulletproof glass to titanium.
Waterjet cutting is a machining process. A high-pressure pump can pump up to 3 liters of water per minute through a 0.28 millimeter water nozzle. This creates a fine jet with extremely high energy density, which is perfect for cutting all kinds of materials.
With pure water cutting, the water is the separating tool. It is especially easy to cut soft materials with this procedure, including paper products, sealing materials, plastics, foams, textiles, and food. Pure water cutting is extremely precise: the water jet can be finer than 0.1 millimeter and it allows the cutting of fine contours, sharp angles, and tight radii.
A waterjet cutting machine also cuts hard materials, such as metal, stone, glass, or ceramics. For this, the water jet must be mixed with a cutting medium (abrasive) – for example, garnet sand. This procedure uses the abrasive jet as the separating device. The water jet serves to speed up the abrasive particles. Waterjet cutting with abrasive is comparable to microchipping.
