Rotary forging is a forging technology which uses a combination of two actions, rotational and axial compression movement, for precise component forming. This technology enables greater use to be made of materials, minimizing (in some cases eliminating) machining and welding operations. Rotary forging requires less force than conventional forming presses, due to a reduction in contact and friction: resulting in smaller presses and simpler tools.
Benefits of rotary forging include shorter cycle times, better mechanical properties from the superior working of the material and high material utilization. All this is done with very cost effective tooling.
Some main advantages of rotary forging, when compared with conventional methods, include: greater dimensional accuracy, better surface finish quality and material hardening and optimized grain structure.
