Generally, the rotating body can be used as a rigid body to balance, in which the larger diameter and smaller width can be used as a static balance.

一般的旋转体可以作为刚体进行平衡，其中直径较大、宽度较小者可以只作静平衡。

This operation creates a tapering of the workpiece via the use of a rotating hammer, which produces stepped columns and shafts of declining diameter.

这次行动创造了一个楔的工件通过使用旋转锤，生产，加强栏目和竖井下降的直径。
