Abstract (en)
A method for ultrasonic cleaning of a part (60, 600) which comprises: applying a cleaning solution on a surface (65, 650) of a part (60, 600) to be cleaned; moving (M) a device (10, 10', 100) comprising a sonotrode (4, 4', 40, 50) along said surface (65, 650), maintaining a distance (D) between said surface (65, 650) and the output surface (4e, 4e', 40e, 50e) of the sonotrode (4, 4', 40, 50) closest to said surface (65, 650); applying ultrasonic vibration (V) by the output surface (4e, 4e', 40e, 50e) of the sonotrode (4, 4', 40, 50), wherein the applied ultrasonic vibration (V) has a certain vibration amplitude; as a consequence of said ultrasonic vibration (V), generating a linear homogeneous column (20) of cleaning solution between said output surface (4e, 4e', 40e, 50e) of the sonotrode (4, 4', 40, 50) and said surface (65, 650) and exposing said surface (65, 650) in contact with said linear homogeneous column (20) of cleaning solution to cavitation, thus removing dirt (70) from said surface (65, 650).
