In the article the modern technological methods to improve the strength of crankshafts. Proposed experimental scheme of strengthening and stabilizing vibromashining of machine crankshafts. It has been established experimentally that the vibration impact processing is achieved by uniform hardening of the surface layer of all elements of the details, finish and rounding of sharp edges, smooth transitions, the exclusion of non-rigid shafts with leashes in the electoral obkatyvaniem of radius machining of large parts.
