Jikuhidai is a type of incremental plasticity processing that forms an enlarged area by applying axial compressive stress and repetitive alternating tensile and compressive stress through rotary bending of the shaft material.
- Low processing energy enables high plastic deformation.
- Enlargement ratio of 1.6D and enlargement width of 1.0D relative to the material diameter are enabled in this cold-working process.
- Thanks to fewer machining and grinding processes, waste material is greatly reduced and energy and resources are saved.
Partial diameter enlargement (Jikuhidai) processing enables material saving; thus it achieves lower costs when compared with machined products.
