Abstract

An apparatus for surface blasting gas turbine blades in the area of their blade roots includes a vibrator with an oscillating surface oriented so that the oscillating surface extends essentially in the horizontal direction. A processing chamber for receiving the blade root adjoins the oscillating surface. The processing chamber is embodied such that the turbine blade is orientable, during the blasting, with a profiled support surface of the blade root extending at least temporarily essentially parallel to the oscillating surface of the vibrator.
