The photo shows the hardening station of an automobile power train CVJ
(constant velocity joint) outer surface induction hardening and
reheating machine.

The hardened ares are the outer stem and cup grooves.
As seen in the photo, as the workpiece rotates the stem is induction heated.

The brown heating coil around the workpiece is our original semi-open line coil.

The benefits of our line coil include:
- deep hardening depth in the curved corners of multi-diameter shafts
- continuous case pattern over the shaft, curved, and flange sections
to prevent soft areas and achieve durability
- simple loading and unloading for short cycle time

With these features, this machine achieves a cycle time of
under 30 seconds per workpiece.
