Pressing process potentialities due to the use of conical mandrels and drive of rotation are considered. It is shown that combined loading in the pressing with torsion results in reduction of contact stresses and pressing force by 30%. The thick-walled tubes with the small diameter holes may be produced by the proposed process version. Hot pressing with inverse metal flowing is simulated by the lead cylindrical hollow blanks.
