1. Generate Pressure
An ultrahigh-pressure pump generates a stream of water with pressure rated up to 94,000 psi (6,480 bar).
To put it into perspective, a fire hose contains a pressure of 390 to 1,200 psi (20 to 84 bar).
2. Convert Pressure into Velocity
This pressure is converted into velocity via a tiny jewel orifice, creating a stream as small as a human hair which can cut soft materials.
3. Introduce Garnet
To increase cutting power by 1,000 times, garnet is pulled into the supersonic waterjet stream.
Water and garnet exit the cutting head at nearly four times the speed of sound, capable of cutting steel over one foot thick.
