The photo shows our motor rotation shaft gear hardening machine.

This machine simultaneously hardens two Φ10, 100mm shafts
with a cycle time of 16 seconds.

Installed in-line at a motor production plant, the machine receives
the workpieces from the previous process,
automatically hardens the workpieces, and sends them to the next process.

The workpieces are loaded from the port to the left (near the bottom
of the control panel).
They are hardened at the left-hand station, after-cooled at the center station,
and air blowed at the right-hand station, before being unloaded from the port
on the right.



To achieve hardening quality and short cycle time, the workpiece,
a multi-diameter shaft. and is hardened by one-shot hardening
using our semi-open line coil to create a even casing along the workpiece's
outer diameter.


※In comparison, scan hardening using a ring coil requires longer cycle time,
can cause overheating at the shaft corners, and have insufficient case depth
at the curved parts of the shaft.


By exchanging the coils and jigs, this machine can several different types
of workpieces.
