A water jet cutter is a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance.
WATER JET CUTTER
It is often used during fabrication or manufacture of parts for machinery and other devices in a diverse number of industries from mining to aerospace where it is used for operations such as cutting, shaping, carving, and reaming.

WORKING PRINCIPLE The cutter is commonly connected to a high-pressure water pump where the water is then ejected from the nozzle, cutting through the material by spraying it with the jet of high-speed water. Additives in the form of suspended grit or other abrasives, such as garnet and aluminum oxide can assist in this process.
