ABSTRACT:
A cutting head for a water jet cutting machine includes a base with a bore and an orifice member having an inlet, an outlet, and a passage extending between the inlet and outlet which increases velocity of fluid flowing through the passage to form a fluid jet. A wear insert has first and second ends, a passage extending between the two ends, the body second end being connected with the base and the body first end supporting the orifice member. A fluid focusing device includes a tubular body with a central passage having inlet and discharge ports, the tubular body being disposable within the base bore such that the body inlet port is fluidly coupleable with the orifice outlet. The tubular body and/or the base are/is configured such that the tubular body is separately positionable at one of a plurality of discrete, predetermined angular positions about the base bore axis.
