The photo shows a reduction gear hold flange induction hardening
and reheating machine.

With one converter supplying power to three hardening machines,
this system is able to harden and reheat flanges of different specifications
in parallel.

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

A robot loads the workpiece from the front port.

Each machine is operated under separate settings to achieve
high productivity and quality.
