The photo shows the hardening station of a truck powertrain axle shaft induction hardening machine.

The multi-diamater axle shaft surface is evenly heated using our
semi-open line coil.

In the photo, the quenching jacket is raised, but during the actual process,
the jacket rotates 90° forward and moves down to the workpiece
for spray quenching.

The horizontally oriented workpiece is held by the centering unit,
then rotated by the straightening roller from below during heating
and quenching.

This method achieves hardening with low run out for thick, long,
and multi-diameter shafts.
