The photo shows our truck powertrain axle shaft induction hardening
and reheating machine.

※At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.

In the photo, the rotating shaft is induction hardened using our
semi-open line coil.

The green device above the workpiece is the heating coil and the gold devices
in front of and behing the workpiece are the quenching jackets.

To quickly quench the entire shaft, two large volume spray jackets are placed
on both sides of the workpiece.

Even considering the large size of the workpiece, this machine achieves
a cycle time of under 2 minutes for hardening and reheating one workpiece.
