Abstract: A press for metal working of cylindrically shaped metal ingots or billets. The press comprises a longitudinally extending hollow tubular member in which a pair of cylinder end members are supported. The two cylinder end members divide the interior of the tubular member into a cylinder portion therebetween and a working portion. A mandrel, aligned with the axis of the tubular member, is provided in the working portion of the tubular member and is connected to a piston provided in the cylinder portion. A die means having a billet chamber and a longitudinal passage therethrough to permit passage of the mandrel into and through the billet chamber is supported in the working portion of the tubular member so as to have the axis of the billet chamber and the longitudinal passage aligned with the axis of the tubular member. Supply means are provided for supplying fluid to the cylinder portion of the tubular member to drive the piston longitudinally between the two cylinder end members and accordingly the mandrel to perform the metal working on the billet.
