AIRFOIL MACHINE COMPONENTS POLISHING METHOD

摘要

A polishing method is described for polishing a machine component comprising at least one airfoil portion comprised of a suction side, a pressure side, a leading edge and a trailing edge. The method provides for arranging the machine component in a container and constraining the machine component to the container. A polishing mixture is added in the container, and the container is caused to vibrate together with the machine component constrained thereto, thereby generating a polishing mixture flow along the airfoil portion until a final arithmetic average roughness is achieved.

1. A method for polishing a machine component comprising at least one airfoil portion comprised of a suction side, a pressure side, a leading edge and a trailing edge, the method comprising:
arranging the machine component in a container and constraining the machine component to the container; adding a polishing mixture in the container, the polishing mixture containing at least: abrasive powder, a liquid and metal particles; and vibrating the container and the machine component constrained thereto, thereby generating a polishing mixture flow along the airfoil portion until a final arithmetic average roughness equal to or less than 0.3 μm is achieved on at least a portion of the airfoil portion and preferably on the entire airfoil portion, maintaining the dimension and shape of the airfoil portion substantially unaltered.
