Six main process characteristics to water jet cutting
There are six main process characteristics to water jet cutting:
Uses a high velocity stream of Ultra High Pressure Water 60,000–90,000 psi (420–600 MPa) which is produced by a high pressure pump with possible abrasive particles suspended in the stream.
Is used for machining a large array of materials, including heat-sensitive, delicate or very hard materials.
Produces no heat damage to workpiece surface or edges.
Nozzles are typically made of sintered boride or composite tungsten carbide.
Produces a taper of less than 1 degree on most cuts, which can be reduced or eliminated entirely by slowing down the cut process or tilting the jet.
Distance of nozzle from workpiece affects the size of the kerf and the removal rate of material. Typical distance is in (3.0mm).
