In article on the basis of the analysis of dynamic methods of finishing — strengthening processing of surfaces plastic deformation suggested a technique of hardening of a surface of cogwheels of the drive of spherical mills. Experimental works on superficial and plastic deformation of a surface of a shaft from steel of 35L are performed. Researches were carried out on the lathe with various modes of processing speed of rotation of preparation, effort of pressure of an roller and feed speed. During experimental works, parameters of surface hardness and roughness were registered. Surface hardness was measured up to the depth of 2 mm. On the basis of the experimental data, graphs with the above mentioned parameters are represented.
