强力旋压是具有无切削、材料利用率高、表面光洁度好、尺寸精度高和能够细化晶粒、提高零件强度等优点的压力加工新工艺。强力旋压按金属轴向流动方向,又可分为正旋和反旋两种。在机械加工行业中,有大量不带底多台阶的薄壁筒形件或任意曲 Strong spinning is a non-cutting, high material utilization, surface finish, high dimensional accuracy and can refine the grain, improve the strength of parts such as the advantages of pressure processing new technology. Strong spin by metal axial flow direction, can be divided into two kinds of positive and negative spin. In the machining industry, there is a large number of thin-walled cylindrical parts or any other song without multiple steps
