This photo shows out automobile engine crankshaft induction
hardening machine.

This machine is installed in-line at an engine plant.
It receives the workpiece from the previous process,
performs hardening automatically, and sends the workpiece
to the next process.


The workpiece is loaded from the port on the right.
First the pins are induction hardened at the right station,
followed by the journals at the left station.
Finally the work is unloaded from the port of the left.


This particular machine is specified for flat hardening of
4-cylinder crankshafts,and shows the common features
of our machines, compactness and short cycle time.

As a result, it has a cycle time of under 45 seconds per cycle
for extremely high productivity.
