 |
|
|
 |
Reduction of the diameter with smaller taper angle: This kind of forms is produced by . The length of the formed area is unlimited. The maximum possible taper angle is about 10° per side. |
 |
 |
|
|
 |
Reduction of the diameter with steep taper angle: Angles steeper than about 10° per side are produced by . This swaging method permits taper angles of up to 90°. |
 |
 |
|
|
 |
Reduction between the workpiece ends: These forms are also produced by . |
 |
 |
|
Non-circular external forms: In addition to various circular forms, rotary swaging can be used to produce circular forms from either non-circular material or from circular material. Conversely, circular forms may be produced from non-circular starting material. |
