	This paper deals with the issue of numerical modelling of the piercing process of a thick–walled bush in a two-rolled skew rolling mill, equipped with guiding devices of Disher’s type. After a short characteristic of the subject matter, the worked out geometrical model of the process was discussed, with taking into consideration kinematics of tools movement and thermal phenomena present in metal during forming. Next, results of calculations were presented in form of fields of strain, damage criterion and temperature. Distributions of force parameters acting on particular tools during the process of bush rolling were also given.
