The photo shows the double axle vertical scan hardening station of
an induction hardening machine for automobile transmission parts.

The workpiece, a clutch release fork (clutch lever), is hardened
at the two tips by semi-open coils.

After heating, the workpiece is carried down and quenched outside of the coil.

The green plate seen behind the coil is the quenching jacket,
which sprays quenching water from diagonally above the workpiece.

In addition to one-shot hardening as seen in the photo, the coils and jigs
can be exchanged for vertical scan hardening as well.
