Zusammenfassung:	An improved system for advantageously utilizing the destructive forces of cavitation for the erosion of solids which comprises forming a fluid jet by directing a fluid through a restricted orifice at a speed sufficient to form vapor cavities in the fluid jet, surrounding the fluid jet with a liquid medium, and impinging the fluid jet against the solid at a distance from the orifice where the vapor cavities collapse.
