The picture shows the pin and journal hardening station of our
all-purpose crankshaft hardening machine, which treats crankshafts
for automobiles, agricultural machinery, construction machinery, and more.

The machine can be adjusted for various types of crankshafts by
exchanging and repositioning the coils and jigs.

During hardening, the workpiece is rotated and the coils follow the
eccentric motion of the pins.

※ As seen in the photo, two pins out of phase with each other are each
followed and heated by a coil.

Through this method, our hardening technology is able to achieve:
・low runout
・even casing
・short cycle time
・compact machine design

Developed based on our extensive designing know-how and hands-on
experience, our heating coils are guaranteed for 20,000 shots.
