在过去的25年里，一种制造薄壁、高精度管状零件的新方法得到了应用：使用滚珠的管旋压。大多数工艺设计是凭经验或基于工业经验完成的。本文给出了一种理论过程分析的方法，它涵盖了感兴趣的领域，如过程区的几何形状，接触表面，力，扭矩，功率和工作。特别重要的是滚珠尺寸、轴向进给和滚珠数量之间的关系，它决定了零件的表面质量。功率估算在筒形件旋压装置的设计中可能是有用的，筒形件旋压装置通常需要比常规熨烫少得多的功率。实验数据与本文给出的算法的计算机应用计算值之间具有良好的相关性。
Over the last twenty-five years a new method of manufacturing thin-walled, high-precision tubular parts has been applied: tube spinning using balls. Most of the process design is done empirically or based on industrial experience. This paper gives a method of theoretical process analysis, which covers areas of interest such as the process-zone geometry, the contact surfaces, the force, the torsional moments, the power, and the work. Of special importance is the relationship between the ball size, the axial feed and the number of balls, which determines the surface quality of the parts. Power estimation might be useful in the design of tube spinning devices, which usually require much less power than conventional ironing. Good correlation is observed between reported experimental data and values calculated by the computer application of the algorithm given in this paper.
