Abstract

A device for surface blasting, e.g., for ultrasonic shot blasting, components, e.g., gas turbine components, includes at least one vibrator having an oscillating surface, e.g., having at least one ultrasonic sonotrode, the or each oscillating surface of the or each vibrator being adjoined by a machining chamber for receiving a section to be blasted of the component to be machined. The machining chamber is bounded in its cross-section by at least three sides, e.g., by at least two substantially vertical sides and by at least one substantially horizontal side. At least the substantially vertical sides of the machining chamber are formed by oscillating surfaces of in each case one vibrator.
