Abstract

The present invention provides a novel method and apparatus for fluid cutting by ejecting a fluid by a Coanda spiral flow generated through a pressurized fluid. The apparatus comprises a rotatable and movable Coanda spiral flow generating nozzle having an annular slit for introducing a pressurized fluid transversely to a nozzle ejecting port and a curved wall running from said slit to said ejecting port. Cutting efficiency is greatly improved and wear resistance of a nozzle is excellent. When using hard cutting particles, they are uniformly dispersed throughout the fluid.
