The photo shows the heating station of an automobile engine
camshaft pump cam induction heating machine.

To austemper the ductile iron pump cam, the cam is heated
to over 1,100℃ and quenched in the adjacent salt bath.

Pictured to the right are the transistorized converter and control panel,
and to the middle and left are the hardening machine and matching panel.

Loading/unloading is done by robot, and 2 workpieces are heated
at the same time. As a result, 2 workpieces are treated in under 1 minute.


For austempering, the heated workpiece is quickly unloaded
by the robot and transported to the salt bath.

This machine was designed for extreme compactness,
as the quenching water circuits in typical hardening were not necessary.
