What is Rotary Forging? Rotary Forging is a metal "roll-forging" process that utilizes a special die arrangement that continuously deforms a small area of the work-piece at a time, incrementally forming the entire part. Rotary Forging, a true rolling process, is a more efficient metal forming process, in that it requires less force and generates less heat and die wear then conventional closed die forging. In Rotary Forging, the axis of the upper die is tilted at a small angle with respect to the lower die; the angled die arrangement creates a much smaller contact or working area when compared to the total part. Both dies rotate, rolling circumferentially around the work-piece continuously deforming it until the final shape is formed. Because the force necessary to produce deformation is directly proportional to the area over which it acts, rotary forging only requires about ten percent of the force required by conventional closed die forging techniques.
This unique forging method coupled with precision servo drives and servo hydraulics is capable of consistently producing complex net or near-net shape parts to within 25 micron accuracies in very challenging and often very expensive exotic materials.

What is Rotary Forging?
Rotary Forging is a metal roll-forging process that uses a special die arrangement to continuously deform a small area of the work-piece at a time, incrementally forming the entire part. The axis of the upper die is tilted at a small angle relative to the lower die, and both dies rotate, rolling circumferentially around the work-piece until the final shape is formed.
How is Rotary Forging different from conventional closed-die forging?
Because rotary forging deforms only a small contact area at a time instead of the whole part at once, it requires only about ten percent of the force needed by conventional closed-die forging, and generates less heat and die wear.
What accuracy can Rotary Forge's machines achieve?
Combined with precision servo drives and servo hydraulics, Rotary Forge's machines consistently produce complex net or near-net shape parts to within 25 micron accuracies, including in challenging and expensive exotic materials.
