In most systems being built today, a venturi effect is utilized to pull the abrasive into the waterjet. The abrasive pa rticles are accelerated into the stream and then with the stream out the orifice. This type of system appears to be more efficient than previously developed abrasive waterjet systems. The intended use of this system is for micro machining. It can also help accelerate the abrasives in the mixing tube.
Finer openings allow more precise cutting and accelerated water jets.
Decreases the pressure if multiple nozzles are put on one pressure intensifier. The size of the pressure intensifier varies approximately from 20,000psi to 50,000psi. This allows the user to get the pressure required without having to pay a high initial cost. Allows variation in cutting. Higher pressure for harder materials.
