Rotary swaging is a process for precision forming of tubes, bars or wires. It belongs to the group of net-shape-forming processes, of which one of the characteristics is that the finished shape of the formed workpieces is obtained without, or with only a minimum amount of further final processing by machining.

The figure shows the principle of operation of a classical rotary swager. The motorized spindle is slotted, in order to hold the backers and the dies. The spindle passes the backers over the rollers, thus delivering a blow to the dies. In rotary swaging process, the head is fixed.
The dies close over the work piece and form the material. When the backers are in-between two roll positions, the centrifugal forces will move them apart, making it possible for the die to open, while the dies are rotating around the workpiece. The operation continues several times and the result is a reduced round cross section of tube, bar or wire.
This rotary machine can have 2, 3 or 4 dies and can be adapted to swage cold or hot material.
