The photo shows the hardening station of our all-purpose hardening machine
for automobile parts.

This machine has two hardening stations, enabling it to harden
two different types of workpieces when equipped with different coils and jigs.

Treatable parts include:

・Shift fork
・Clutch release fork
・Lever striking
・Bracket

and other such parts for automobile transmission, which have difficult shapes
including curves and teeth.

To treat curved sections, a MOSFET transistorized converter
capable of outputing frequencies of 100~300kHz is used.
