FIELD: technological processes.
SUBSTANCE: invention is related to methods for rounding of turbomachine blades edges formed by at least two adjacent surfaces of blade, in direction of these surfaces, by abrasive treatment. Jet is supplied to blade edge that consists of at least for the most part from abrasive particles. Jet is supplied approximately tangentially to middle line of blade profile in point of middle line crossing with blade edge. Jet and edge are displaced relative to each other in direction along edge provided that part material is removed with rounding of edge in direction of specified surfaces.
EFFECT: improved quality of processing, reduced percentage of rejects, provision of labor force and time saving.
