ABSTRACT:
A surface of the gas turbine blade is smoothed by way of a drag finish process. A first ring-shaped container is filled with a liquid abrasive medium. A second container which is arranged next to the first container is filled with a second liquid abrasive medium. A pivoting arm is arranged between and above the containers and can be pivoted along a pivoting direction. A drag device is arranged on the pivoting arm. The drag device leads a gas turbine blade on a carrier arm through the abrasive medium.
