Forging is a process that makes three-dimentional objects out of materials by crushing, exciting and other deforming procedures.
Various shapes are possible. Consult with us.
Unlike conventional pipe benders that require fixed-radius dies, our CNC Freeform Pipe Bender allows full control over bend radius and angle through programmed processing. This innovative bending system eliminates the need for frequent die changes and enables highly complex bending operations.
Capabilities Beyond Conventional Pipe Bending
With our system, the following bending operations—previously impossible with traditional pipe benders—are now achievable:
Large-radius bends on the scale of several meters (large R bends)
Continuous variable-radius bends (compound R / progressive R) without intermediate straight sections
3D freeform curves by adjusting the axis angle of compound/progressive bends
Bend angles exceeding 180°
Multiple bend radii in a single continuous process—eliminating the need to change bending dies
Seamless 3D Data Integration
If you provide the 3D centerline data of your pipe (designed with straight and arc segments), we can instantly convert it into our proprietary CNC format using our data converter. This allows for rapid prototyping, much like a 3D printer for pipe bending.
Example Processing Program:
D=42.7
L=120 FF=25.00 FE=25.00
R=100.00 T=90.00 P=0.00 FE=25.00 FF=25.00
R=225.00 T=180.00 P=90.00 FE=25.00 FF=25.00
R=100.00 T=90.00 P=0.00 FE=25.00 FF=25.00
L=120 FF=25.00 FE=25.00
Parameter Definitions:
D = Pipe outer diameter (mm)
L = Length of straight section (mm)
R = Bend radius (mm)
T = Bend angle (°)
P = Axis angle at the connection between different R bends (°)
FF / FE = Relative speed of movement along the XY axis (relative to pipe feed speed)

The large dip-quench hardening machine installed in our job heat treat plant
is mainly used for large gears and rollers.
It can treat parts up to 1.8m in diameter.
The photo shows the dip-spray process in action.
At Fuji Denshi, we design, manufacture, and sell induction heating machines
as well as do job heat treatment and prototype development.
The photo shows our stub shaft axle hardening and reheating machine.
The one-shot hardening method using our line coil achieves an ideal case
pattern even with the varying diameter of the workpiece, while saving energy.
The entire length of the workpiece is quenched simultaneously,
ensuring the residual heat over the part's length is even and
preventing cracking and uneven case hardness and depth.
(Even heating / Even quenching)
Heating and quenching are both even over the entire surface,
so runout is kept at a minimum even without the need for a straightening roller.
The residual stress along the axle axis contribues to large increases
in the part's durability and strength.
(2x by comparison)
Scan hardening can easily cause uneven hardness and low axial strength.
Our one-shot hardening requires only half the power of scan hardening to better results.

It receives the workpiece from the previous process, performs hardening
automatically, and sends the workpiece to the next process.
The workpiece is loaded from the port on the right.
First the pins are induction hardened at the right and center stations,
followed by the journals at the left station.
Finally the work is unloaded from the port of the left.
This machine performs flat hardening, which in general is a simpler process,
but to achieve the specified short cycle time of under 50 seconds,
the machine was designed with two converters and three hardening stations
for high productivity.
The photo shows the hardening and reheating stations in a automobile propeller
center bearing shaft induction hardening and reheating machine.
On the right with the green spray quenching jacket is the hardening station.
On the left in the brown box is the reheating station.
※At Fuji Denshi, we refer to tempering as reheating to differentiate from
furnace methods.
The hardening and reheating stations are divided and have separate converters
to achieve a cycle time of under 30 seconds.
This design achieves both compactness and high productivity.
Fuji Denshi's camshaft hardening machine uses our patented eccentric
tracking mechanism.
The coil follows the rotating cam nose to achieve even heating.
Using these technologies, cracking during grinding is prevented
while achieving an even casing and low runout.
The high-speed design also contributes to shorter cycle 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.
We manufacture driveshaft induction hardening machines.

This is our crankshaft induction hardening machine, able to treat crankshafts
for automobiles, agricultural machinery, construction machinery and more.
The machine can be adapted for a variety of crankshafts by
retooling the coil and jigs and other adjustments.
It is also able to perform hardening of split pins for V engine crankshafts.
With manual loading/unloading, after placing the workpiece on the front left jig,
the jig moves to the center and carries the workpiece to the back
of the machine.
In the back station, the pins and journals are hardened.
If the front station, the crankshaft oil hole section is hardened.
After hardening, the work are carried to the center and unloaded to the right.
While being extremely flexible, this machine also has high productivity.
This large dip quench induction hardening machine is installed
in our job heat treat plant.
Outer ring hardening: up to 1800mm diamater, 350mm thickness
Inner ring hardening: up to 1500mm diameter, 150mm thickness
This machine performs one-shot hardening for large gears,
bearing races and more up to the above dimensions.
For gear hardening, this machine features
- even heating by ring coil
- even quenching by dip spray
to minimize runout and cracking.
By heating in two stages, preheating and main heating,
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.
This photo shows out automobile engine crankshaft induction
hardening machine.
This machine is installed in-line at an engine plant.
It receives the workpiece from the previous process,
performs hardening automatically, and sends the workpiece
to the next process.
The workpiece is loaded from the port on the right.
First the pins are induction hardened at the right station,
followed by the journals at the left station.
Finally the work is unloaded from the port of the left.
This particular machine is specified for flat hardening of
4-cylinder crankshafts,and shows the common features
of our machines, compactness and short cycle time.
As a result, it has a cycle time of under 45 seconds per cycle
for extremely high productivity.
[Custom-made Machines]
This is the flange oil seal hardening station of our all-purpose crankshaft
hardening machine, which treats crankshafts for automobiles,
agricultural machinery, construction machinery, and more.
The machine can be adjusted for various types of crankshafts
by exchanging and repositioning the coils and jigs.
In the photo, the flange section of the crankshaft is induction heated
by a ring coil.
The coil is housed in green resin insulation to prevent induction
of the surrounding machine,while the coil is cooled by a continuous flow
of cooling water through its copper piping.
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.
[Job Heat Treatment]
The photo shows the shaft hardening machine in our job heat treatment plant.
The left- and right-hand station are independent, allowing for treatment of
different workpieces.
Shafts from diameter 14~17mm and length 145~180mm can be treated.
Please contact us for your job heat treatment needs.
The photo shows our automobile engine camshaft induction hardening
and reheating machine.
To increase productivity, the machine was designed with two stations,
which alternate between hardening and reheating using one converter.
※At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.
Loading/unloading is done manually. After placing the workpiece
on the front right side jig, a robotic arm carries it to each station.
After hardening, the arm carries the workpiece to the front left port.
This machine also features our patented coaxial coil lead which has
lower lead power loss. The coil lead is shielded from the induced current,
resulting in longer coil life.
The photo shows the heating station of our automobile engine
camshaft induction hardening and reheating machine.
3 coils are used to simultaneously heat 6 cam noses of a V6 engine camshaft.
Our original coil design prevents cracking from overheating of the cast iron camshaft.
The quenching water volume is also controlled to further prevent cracking.
~Camshaft Induction Hardening Reheat Machine②~
As the demands for lighter, stronger, more efficient, and more eco-friendly
engine manufacturing increase, we at Fuji Denshi have supplied over
250 crankshaft hardening machines domestically and overseas.
Our crankshaft hardening technology, based on our semi-open coil
and rotating tracking method, includes numerous innovations which combine
to minimize runout.
Our fillet hardening technology has become a must-have for stonger
and lighter crankshafts.
We strongly encourage manufacturers currently using carburization
to consider our induction technology to improve cost, lead time, and 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 the hardening station of an automobile engine crankshaft
induction hardening machine.
During hardening, the coil follows the pin section of the rotating workpiece
as it heats.
※ As seen in the photo, each pin, out of phase with the others,
is treated by a separate coil.
Through this method, our hardening technology is able to achieve:
・low runout
・even casing
・short cycle time
・compact machine design
In recent years, crankshafts have become smaller and thinner to
improve fuel economy.
The pictured crankshaft is a small, thin model, which also required
fillet hardening of the pins and journals.
Using our extensive designing know-how and hands-on experience,
we achieved the specified fillet hardening by designing the coils to
optimize power control.
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.
For our customers facing induction hardening cracking, let us at Fuji Denshi
resolve your issues.
● Magnetic Particle Testing
A non-destructive inspection method applicable for surface cracks,
forging cracks, hardening cracks of magnetic materials.
● Principle of Magnetic Particle Testing
Similar to magnetizing a nail by winding it with a conducting enamel thread,
the workpiece to be inspected is magnetized. If there are cracks,
each side of the crack will have opposite polarities.
By applying colored or flourescent iron powder liquid to the workpiece,
the powder accumulates in the cracks, making them visible.
● Demagnetization
After inspection, the workpiece must be premagnetized before post-
processing such as grinding.
At Fuji Denshi, our veteran technicians use our magnetic particle testing
equipment to locate cracks undetectable by color spray.
Please contact us with your concerns about cracking.
