At Fuji Denshi, we offer high productivity and quality hardening technology
for not only automobile parts and small parts, but also for large parts.

[Large Gears]
We use a full-circumference one-shot hardening method to achieve
an adequate casing.

[Large Idlers]
Our original semi-open coil is designed to match the shape of the workpiece
to achieve even hardening.

[Original Dip-Spray Quenching]
By submerging the workpiece in quenching water, stirring the water,
and spraying additional quenching water, the entire workpiece is
quenched evenly, achieving an even casing.

[Large Beds]
●Workpieces up to 15m, 40t including columns and beds for machine tools
　Both machine order and job hardening options available

●Automatic Coil Tracking
　For surface hardening, our position sensor measures the gap between
the coil and workpiece surface and the coil is moved accordingly to
maintain a constant distance to achieve an even casing.
