At our job heat treatment plant, we provide a wide variety of processes.

The photo shows a machine tool axle being hardened by our large vertical
scan hardening machine.

The gap between the workpiece and copper colored coil is extremely close.
If the coil gap is too large, the following quality defects can occur.

・For shafts, if the coil is off center, the hardened casing becomes uneven.
・Longer time required for heating increases the risk of overheating.
・The area surrounding the target area is also induction heated,
resulting in power loss.

To prevent these defects, we design coils with the optimal coil gap.

To prevent contact between the coil and workpiece, which can cause a
short circuit and damage the workpiece, the coils are moved to the required
distance from the workpiece before heating.

While time consuming, these check measures ensure the highest quality
hardening process in the industry.
