The photo shows the hardening station in a motor shaft gear induction hardening machine.

Two shafts are induction heated simultaneously by a line coil.

The shafts, each approximately 10mm in diameter and 100mm in length,
are induction hardened in 16 seconds per cycle.

Using our original semi-coil line coil and rotating one-shot hardening method,
this machine achieves a casing along the shaft outer diameter.

※ Ring coil scan hardening requires longer cycle time, can cause overheating
of the corners, and have shallow case depth at the curved sections.

By exchanging the coils and jigs, this machine can process up to 20 shaft models.
