[Custom-made Machines]

The photo shows the hardening station of our one-cylinder
engine crankshaft induction hardening machine.
This type of engine is supplied 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, the crankshaft is rotated while the pin section is hardened.

The gold-colored device hanging to the left is the pin hardening coil,
and the copper-colored device attached to green insulation on the right
is the journal hardening coil.

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