The photo shows the hardening station of a reduction gear hold flange
induction hardening and reheating machine, seen from above.

The outer circumference of the disc-shaped workpiece in the center
is heated by the ring coil.

The workpiece is loaded/unloaded from under the coil.
After the workpiece is set, the jig raises the workpiece into the coil,
where it is heated at a very close distance.

After heating, the jig carries the workpiece down to the quenching position.
Quenching water is sprayed from the surrounding jackets
for quick and even quenching.

This machine is designed to achieve high hardening quality
by optimizing heating time, power, quenching time, and water flow.
