The paper presents experimentalmodel research results on the process of cross-wedge rolling of an axially-symmetrical element (stepped shaft). During research plastic mass on the basis of waxes in black and white colour was used. The aim of this experimental research was to determine the best option of forming in terms of values obtained and the course of forces. Physical examination was carried out using specialist machines, i.e. model and a laboratory cross-wedge rolling mill. Experimental analysis was carried out using billets with the temperature of 15°C, whereas the actual process was carried out for billet from C45 carbon steel of temperature 1150°C. The study compared the dimensions of the components obtained during rolling tests and forming forces obtained in the result of physical modeling with forces obtained during real tests.
