Abstract

A cutting head for a water jet cutting machine has a body removably supporting a holder with an orifice element, and insert with a chamber, and a nozzle having a passage in alignment with the water flow path through the head. The holder has a cone shaped surface that fits into a complimentary shaped cone recess to align the aperture of the orifice element with the axis of a water inlet chamber. The insert is retained within a transverse bore in the body to align its chamber with the axis of the aperture. A griping collet holds the nozzle on the body and aligns the passage of the nozzle with the axis of the aperture so that aperture, insert chamber, and the passage of the nozzle are linearly aligned with each other to form the water flow path through the nozzle.
