[One-Shot Hardening]
During scan hardening, the beginning and end points are heated
and quenched twice, which can cause cracking or soft spots.
In contrast, our one-shot hardening achieves a sufficiently deep casing
around the whole circumference of gears up to 1.8m diameter and 15 module.

[Dip Quench Hardening]
Immediately after heating, the workpiece is submerged in quenching water
and sprayed by quenching water jackets. This prevents the formation of
an air layer around the workpiece and ensures an even casing.
By controlling the water temperature and mixing speed,
the resultant casing can be controlled to high precision.

[Inner/Outer Simultaenous Heating]
The machine can be fitted with two power sources to heat the
inner and outer surfaces at the same time.
