This photo shows the hardening station of our autmobile engine
crankshaft flange hardening machine.

The workpiece is loaded/unloaded from above by robot.

After the workpiece is set on the rotating jig, the coil unit moves forward
to the heating position, and heats the workpiece as it rotates around its axis.

The photo shows the crankshaft flange being heated by the induction coil,
which is behind the green disc-shaped spray jacket.

After heating, the coil unit moves slightly back to the quenching position,
and quenching water is sprayed onto the workpiece from the spray jackets.
