The photo shows our 1-cylinder engine crankshaft induction hardening machine.
The crankshaft is used in engines for agricultural and production machinery.

This machine is installed in an overseas engine plant.
The workpiece is transported from the previous process and hardened.

Loading and unloading is done manually, while door close → coil set →
hardening is automatic.
(In recent years robotics have been implemented for loading and unloading,
resulting in an increase in fully automatic machines.)

In the photo, in the front left is the hardening machine.
In the back right is the incoming panel and transistorized converter.
In the back left is the quenching water tank and air-cooled chiller.

Both pin and journal sections are hardened at the same station,
allowing for a compact machine design.
