Abstract

A method for rounding edges of parts, in particular of turbo engines, is disclosed. An edge to the surfaces is rounded, the edge being created by at least two adjacent surfaces of the part. A blasting jet consisting mostly of abrasive particles is directed at its center approximately tangentially to the angle bisecting line between the surfaces at the edge and is moved at a defined rate of advance in relation to the part along the edge such that there is a defined removal of material of the part with rounding toward the surfaces.
