A technology that has all the advantages of SPD classical methods, with a multiple of increased productivity allowing to replace the processes of finishing with abundant forced cooling method for SPD methods without lubricoolant, developed. Hyper-productive processing SPD technology with application the “quick readjustment” principle allows the processing of different parts surfaces with using fewer amount of equipment. Designed hyper-productive method of SPD processing with a wide spherical burnishing tool without flammable lubricoolants is implemented by OJSC «AvtoVAZ» in main manufacture on automatic finishing of vehicle parts. In order to optimize the treatment with a wide spherical burnishing tool two-way multi-level experiment of packing journals of crankshaft processing conducted in a production environment. As a result of this experiment influence of major processing parameters on the finished surfaces roughness found. Obtained results allow to select particular modes of burnishing according to the required roughness of workpiece.
