The photo shows the hardening and reheating stations in a automobile propeller
center bearing shaft induction hardening and reheating machine.

On the right with the green spray quenching jacket is the hardening station.
On the left in the brown box is the reheating station.

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

The hardening and reheating stations are divided and have separate converters
to achieve a cycle time of under 30 seconds.

This design achieves both compactness and high productivity.
