The developing process of the ultrasonic drill can be divided into two stages.
The existing ultrasonic drill only uses the vibration on front side, and part of vibration on the back side is not used.
Above all, to the best knowledge of the authors, the research about the collision process of the free mass is mostly in the load condition of the ultrasonic drill, which means that ultrasonic drill breaks into rocks and the drill tool is fixed with the rocks.
(2) The rotary-percussive ultrasonic drill works in no-load condition, and the drill tool can vibrate freely along the axial direction.
