Abstract
The present invention provides a spinning method of a work piece in a non-circular cylindrical shape capable of eliminating a swollen part, without causing any creases or depressions on the formed face, by performing spinning to the swollen part produced in a region near the minor axis of the work piece in a non-circular cylindrical shape. A spinning method for spinning the end part of the work piece into a circular cylindrical shape comprises a spindle mechanism provided with a spinning roller at the tip of the spindle and a work piece holding mechanism for holding the work piece in a non-circular cylindrical shape disposed face to face with the spindle mechanism, and includes performing spinning for forming the end part of the work piece into an inclined face inclined so as to gradually reduce in diameter, and then performing spinning on the swollen part in a region near the minor axis of the work piece by displacing the work piece by a prescribed angle in the plane containing the minor axis plane of the work piece in a non-circular cylindrical shape.
