The photo shows a track powertrain axle pipe induction hardening
and reheating machine.

※At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.

The pipe shaped workpiece is orientated horizontally in the hardening station.
This machine is able to treat pipes of various diameter and length
by retooling the machine.

This machine was designed for manual loading/unloading due to
the small lot size of truck axle shafts and the need to treat workpieces
of different specifications.

The green colored unit above the workpiece is the heating coil,
and the gold colored unit under the workpiece is the quenching jacket.

After the workpiece is loaded, the receive jig carries it down,
where it is held by the centering unit.
It is then lifted up, where model identification is done.
The workpiece is then carried under the appropriate coil for the workpiece model
and the coil is lowered onto the workpiece.
The workpiece is rotated while hardened.

Due to the large size of the workpiece, heating and quenching takes a
relatively longer time, but this hardening and reheating machine is able
to achieve a cycle time of 2 minutes per workpiece.
