About Partial Diameter Enlargement Technology "Jikuhidai®"

“Jikuhidai®” is a successive deformation processing method that forms enlargements by applying alternating stress through a process of repeated pulling and compression by exposing the shaft material to compressive stress and rotary bending in the axial direction.
