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.

ADVANTAGES There is no heat generated It does not produce any dust or particles

that are harmful if inhaled. It can be easily automated for production

use High precision - no need for costly

recutting High cutting speeds No need for resharpening tools Very fast implementation from drawing

board to cut piece
