Partial hardening is possible. Minimum heat distortion. Any hardening that it is unique to Diode Laser is possible.
Cylinder inside. Low distorted hardening
Deformation after hardening ： 3μm
It is possible to hardening marked parts
Small diameter hole (Inside hardening)
It is possible to hardening very small hole side.
Pipe inside diameter hardening
It is possible to hardening spirally.
Groove portion hardening
Hardening for side and bottom of groove.
Internal gear hardening
