Results of researches on improvement of technological process of cut-in centerless grinding of crosspieces of driveshafts of cargo cars are given in work for the purpose of ensuring high physicomechanical parameters of quality of polished surfaces. The results providing improvement of quality of surfaces of pins of crosspieces of driveshafts are received. Results of researches of influence of elements of modes of cutting of cut-in centerless grinding on the microhardness of polished surfaces are presented. Expediency of use of recommended modes of grinding is shown when processing crosspieces of driveshafts. The technique of research of a physicomechanical condition of polished surfaces is developed. Mechanisms of formation of microhardness of blankets of polished surfaces depending on the speed of grinding, speed of rotation of leading circles, minute cross giving, an allowance on grinding and nursing time are revealed.
