带纵向内筋的薄壁筒形件就是适应这一需要而出现的。
Thin-walled tubular parts with longitudinal inner rib can satisfy the demand.
因此，通过多道次滚珠旋压可实现大减薄量薄壁筒形件的旋压成形。
Therefore, the spinning of thin-walled tube with large thickness reduction can be realized through multi-pass ball spinning.
作为一种连续局部塑性成形工艺，滚珠旋压被应用于制造铝合金薄壁筒形件。
As a successively and locally plastic deformation process, ball spinning is applied for the purpose of manufacturing thin-walled tubular parts of aluminum alloy.
