In this paper, new die which improves the process limited is proposed for nosing process of the circular tube. The usual dies are the symmetrical axis and cone. The asymmetrical conical dies which possess the relief in circumferential direction were devised. It did experiment of 3 sorts. As the first method, it did the press forming by the usual die. As the second method, while turning the circular tube to the usual die, it did press forming. As the last method, while turning the circular tube, it did the press forming by the new die. As a result, the load was reduced with the die which this paper proposed, and it was confirmed that a processing limit was improved.
