The Nisshin Rotary Chuck is a game-changer for precision grinding, helping manufacturers achieve higher accuracy and efficiency with minimal setup effort.
The product shown in the picture is a cut sample of a small diameter precise ball screw.
The bottom (diagonally right) product has been processed using an ordinary quenching technique.
The top (center) product’s appearances are exactly as before processing.
However, inner portion is quenched completely.
As one can see, our “non-oxidation quenching” will not cause any scale as ordinary quenching.
This method requires no after treatment as shot blast.
In other words, scales and sands which can cause reduction of after treatment preciseness will not be problematic.
We sale high frequency induction heating machineries.
This machine will utilize the induction heating principle which has effects on improving surface hardness and improved wear resistant.

The photo shows the hardening station of a vertical scan induction hardening machine
for shafts used in motors, generators, and alternators.
This automatic machine can induction hardening various motor shafts from
automobile alternators to vessel generators.
Our vertical scan hardening machine can be designed to move not only the workpiece, but also the coil and power transformer unit.
With this design, we decreased the size of the hardening station and
the entire machine as well as made loading and unloading easier.
As a result, this machine performs high quality hardening while
decreasing operation time.
The photo shows our production machinery bed hardening machine during
automatic coil changing.
Our bed hardening machine's automatic coil changer reduces retooling time
and necessary work.
In the photo, the previous coil is returned to the coil station and the changer
picks up a new coil.
Our gate model bed scan hardening machine is the first machine in the world
to be installed with this device.
This large dip quench induction hardening machine is installed
in our job heat treat plant.
Outer ring hardening: up to 1800mm diamater, 350mm thickness

the case depth is deep even in the gear grooves.
Please contact us with your job heat treatment needs.
We manufacture bed induction hardening machines.
The pictured hardening machine is for industrial machine beds.
Our bed hardening machine features our automatic coil tracking system,
which maintains the gap between the coil and workpiece
by sensor during the automatic hardening process.
As seen in the photo, the extremely small gap between the coil
and workpiece is maintained throughout the process.
The power consumption by the workpiece is highly efficient,
while achieving an even casing, ensuring high quality and energy savings.

※ Inner diameter: up to Φ1500, thickness 150mm
[Material] steel (S45C), stainless steel (SUS304), etc.
[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.
[Job Heat Treatment]
The photo shows the large parts hardening machine in our heat treatment plant.
The part size can be visualized by comparison with the workers
standing behind it.
This machine can treat parts up to 15m in length and 40 tons in weight,
which is the heaviest weight permitted to be carried on Japanese roadways.
Large parts treated with this machine include machine beds, columns,
and slide guides.
[Custom-made Machines]
The pictured machine is our horizontal scan induction hardening
and reheat machine for construction machinery shafts.
At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.
The pictured machine is specified for front loading and unloading.
Loading is performed by robot and unloading is done automatically
by jigs and chute for a simple yet highly productive design.
The photo shows the hardening station of our all-purpose single axle
double bed vertical scan induction hardening machine.
Our vertical scan induction hardening machines typical move the coil
during scanning, but this machine was designed for the workpiece
to move as specified by our customer.
The machine also can perform one-shot hardening, as seen in the photo.
The coil heats the workpiece from above and the jacket quenches it from below.
By rotating the workpiece while heating with our line coil, the multi-diameter
workpiece is heating along the whole circumference.
The photo shows our vertical scan induction hardening machine for shafts
used in motors, generators, and alternators.
This machine can treat various shafts including for automboile alternators
and ship generators.
By setting parameters including output power, frequency, coil type,
workpiece size, feed speed, and quenching water flow,
our vertical scan hardening machine achieves high repeatability
As a result, runout is kept to a minimum for high quality hardening
and reduced operation time.
The photo shows our large part hardening machine in our heat treat plant.
This machine can treat parts up to 15m in length and 40t in weight.
The machine treat beds, columns, and slide guides, among other parts.
Our specialized technology for surface hardening controls quenching
to ensure minimum runout.
[Job Heat Treat]
The photo shows hardening of the teeth of a gear.
After heating, the workpiece is lowered into the quenching water,
where it is sprayed by additional quenching water to achieve an even casing.
We have a large-scale and small-scale dip-spray hardening machine
in our heat treat plant, which together can treat parts up to diameter 1.8m.
We have also manufactured and installed this same machine in our customer's plant.
The photo shows cut samples of various machinery parts hardened
by our induction hardening machine.
The gray area of the cross section is the hardened casing.
As seen in comparison with the pictured cigarette box, the parts
are surprisingly small and the hardened areas are complexly shaped.
At Fuji Denshi, we apply our induction heating technology to meet
our customer's heat treat needs by supplying machines or providing
in-house job heat treat.
One of our specialties is heat treatment of large workpieces such as
construction machinery slewing bearing and machine tool beds and columns.
~Induction Hardening Cut Sample IH Heat Treat Automobile Parts

[Large Bed Induction Hardening Machine:] 1100kW/10~100kHz
Maximum workpiece dimensions: W 3m x D 15m x H 2m
This hardening machine can treat workpieces up to 40t in weight
such as gears, crankshafts, columns, and beds.
By controlling the gap beween the coil and workpiece surface via sensor,
the coil automatically tracks the workpiece surface for stable hardening.
This is an original technology not available anywhere else in Japan.
Please consult us for hardening of any large parts.
The photo shows the hardening station of our horizontal hardening
and reheating machine for construction equipment shafts.
This machine automatically hardens mutiple types of shafts.
In the majority of our scan hardening machines, the workpiece is kept
stationary while the coil and power transformer unit moves,
a design technologically superior in general.
However, the shafts treated by this machine are relatively short.
To minimized cycle time, a horizontal scan design was chosen
with the focus on the loading/unloading speed of the shafts.
The workpiece is loaded horizontally by robot, then rolls along
the guide rail to the receive jig. After hardening, the workpiece
rolls along the unloading guide rail to the unloading station.
The photo shows a cut sample for a guide rail for linear accuators
hardened by our induction hardening machine.
The pattern seen on the cut sample shows that the shaft has been
hardened down to the bottom of the guide rail grooves.
The most difficult part of hardening this workpiece is preventing runout.
During scan hardening of the groove, the concave guide rail slightly twists.
Runout in the vertical or horizontal direction only can be corrected,
but twisting is not so easily corrected, which in general resultsin many
defective hardened parts and increased lead time.
Through extensive trial and error, we at Fuji Denshi developed
a combination of hardening machine, coils, and jigs to minimize runout.
We offer similar solutions for optimal hardening of a wide variety of workpieces.
Please contact us with your hardening needs.
The photo shows a cut sample of a small diameter ball screw,
shown in comparison with a 10-yen coin.
Our method achieves an adequate case depth in the ball groove
without overheating even for small ball screws.
We design each coil custom-made and calibrate each machine
to meet our customer's specifications.
Please contact us with your induction heat treat needs.
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.
