The Open Die Forging Process |
|
|
Steps to produce a typical spindle-shaped part: |
|
|
 |
Rough forging a heated billet between flat dies to the maximum diameter dimension. |
 |
A "fuller" tool marks the starting "step" locations on the fully rounded workpiece. |
|
|
|
|
 |
Forging or "drawing" down the first step to size. |
 |
The second step is drawn down to size. Note how the part elongates with each process step as the material is being displaced. |
|
|
|
|
 |
"Planishing" the rough forging for a smoother surface finish and to keep stock allowance to a minimum. |
