METHOD FOR SPIN FORMING ARTICLES

摘要

A method of spin forming, comprising the steps of: providing a tool (20) having a first plurality of forming rollers (34, 36) spaced at a second plurality of distances from a spin axis (30); spinning around the spin axis at least one member of a set comprising (i) a work piece and (ii) the tool; and engaging the tool and a first end of the work piece. The method allows increased diameter reductions of a free end of a work piece in a single forming operation without collapse of the end of the work piece.
