This paper gives an account of a new project for the design and production of a radial cyclic forging machine. This new design considers the advantages of its predecessor and of modern trends within the engineering industry. The use of this machine could enable the considerable reduction of production wastes. Besides the cold cyclic technology implemented in this machine, it will also allow for the increase in energy efficiency, for the minimum capital investments.

The technology of the shell case rolling into the rough pipe on an automatic mill of the pipe-rolling plant PRP 220 was considered. In case of the pipe rear end stability losing for a special thin-walled assortment of rolling products the theoretical research was carried out based on the FEM. As the result of the research the nature of such flaw as a “fin” on the end of the pipe was investigated, the evaluation of the loading on the automatic mill for the PRP 220 was obtained for different process parameters.
