Beschreibung
Zusammenfassung:	A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.
