Abstract:
1. A fluid focusing device for a cutting head of a waterjet cutting machine, the cutting head including a base with a bore having a central axis extending through the bore and an orifice member coupled with the base, the orifice member having an outlet and a passage for increasing velocity of fluid flowing through the passage so as to form a fluid jet discharged through the outlet, the focusing device comprising: an elongated, generally tubular body with a body axis and a central passage having an inlet port and a discharge port, the tubular body being at least partially disposeable within the base bore such that the body inlet port is fluidly coupleable with the orifice member outlet, the tubular body being configured so as to be separately positionable at each one of a finite number of discrete, predetermined angular positions about the base bore axis, the inlet port being at least generally aligned with the orifice member outlet at each one of the finite number of positions of the tubular body about the base bore axis such that the fluid jet flows from the orifice member outlet through the inlet port and into the central passage.
