This is an induction annealing machine for studs, a type of shaft jig
for cam followers.

After hardening the entire surface by carburizing, only the screw section
is annealed by induction.

As seen in the photo, the workpiece is loaded manually from the left
and carried by conveyor to the annealing station.
Annealing is done by continuously heating the workpiece as it passes
through a tunnel coil.
Then it is quenched at the after quenching station and automatically
unloaded by conveyor.

The machine was developed to replace the older model that used
vacuum tube converters and turntables.


We continue to develop machines with high productivity using
the simplest possible design.
