Abstract
PURPOSE: To prevent occurrence of flaws and tears in a blank under spinning by making a tail stock to double structure consisting of a stem and an outer cylinder and forming a recessed face at the tip of the outer cylinder.
CONSTITUTION: A blank 1 is thrusted against a mandrel 2 by a stem 8 and an outer cylinder 7 of a tail stock 3 at the same time. When the blank 1 is pressed against the mandrel 2 by a working roller 4 while rotating the mandrel 2 and tail stock 3 coaxially, the blank 1 is pushed down. With this, the outer cylinder of the tail stock 3 advances to press the blank 1 at all times. Finally, the corner part 6 is held by the mandrel 2 so that it hold the blank 1 completely. By this mechanism, spinning is made without causing tears in the blank 1 in the corner part even when bending force is generated in the blank 1 by the working roller 4.
