The invention relates to a device and a method for ultrasonic deburring of an object, in which ultrasound is generated by an ultrasonic generator and introduced into an object to be deburred via a sonotrode located in an ultrasonic transmission medium, the sonotrode at a defined distance between the sonotrode tip and the surface of the The object is arranged and aligned in a defined manner relative to the surface of the object, such that the longitudinal axis of the sonotrode is aligned with the surface of the object at a predeterminable angle, in which Rayleigh waves are generated in the surface of the object. In contrast to previously used devices and methods for ultrasonic deburring, this enables more effective ultrasonic deburring, in particular deburring of high-strength materials.
