The photo shows the hardening station of our automobile camshaft
induction hardening and reheating machine.
In the photo, two noses of two camshafts are being induction heated.
After heating, the coils move laterally and at the same time
the quenching jackets moves from the left over the cams
to rapidly quench them.
Our camshaft hardening machine uses our patented eccentric tracking
mechanism, where the hardening coils follow each cam nose as the shaft
rotates to achieve even heating.
Our originally developed coils are also designed to prevent temperature
difference over the cam surface.
The quenching jackets are designed to even quench each cam without
using excess quenching water.
Using these technologies, we are able to reduce cracking during hardening
as well as cracking during grinding caused by uneven stress, while achieving
an even cashing and low runout.
~Camshaft Induction Hardening Reheat Automobile Parts IH Machine②~
The photo shows the heating station of an automobile engine camshaft
pump cam induction heating machine.
To austemper the ductile iron pump cam, the cam is heated to over 1,100℃
and quenched in the adjacent salt bath.
To effectively heat the triangular shaped target area,
the rotating workpiece is heated with low frequency using
a multi-turn coil until a certain depth is reached.
In the photo, the pump cam is heated to a depth close to the shaft axle.
After thorough calibration, we were able to meet the severe heating
specifications of minimum 1,100℃ and range ±20℃ for two differently
shaped target areas.
The photo shows the single rotating axis hardening station of
an induction hardening machine for automobile transmission parts.
The workpiece, a clutch release fork (clutch lever), is rotated

due to the small lot size of truck axle shafts and the need to treat workpieces
of different specifications.
The green unit under the workpiece is the heating coil.
To minimize runout, this machine is equipped with a semi-open line coil
and a straightening roller.
The box-shaped unit in the back of the hardening station equipped with hoses
is the quenching jacket.
During hardening, the quenching jacket rotates forward 90˚ and the center door
closes to prevent quenching water from splashing.

(80kHz, 100kHz, 200kHz, 300kHz) to treat various parts.
It also features an interlock circuit control to allow treatment of
various parts in succession.
[Custom-made Machines]
The photo shows an automobile steering upper shaft induction annealing machine.
After forming with a press, the desired sections of the hardened workpiece
are induction heated for annealing.
The workpiece is carried by the belt conveyer and positioned by the centering unit.
Then it is lifted into the machine, inserted into the coil, and heated.
The coil is specially designed to heat two workpieces simultaneously.
This photo shows the heating station of our automobile transafer shaft
and helical shaft induction annealing machine.
After the entire surface is hardened by carburizing, only a section
is annealed by induction.
The workpiece is automatically loaded into the annealing station,
and after annealing is automatically unloaded.
By synchronizing loading and unloading, a shorter cycle time was achieved.
This machine is one example of our simple yet highly productive
induction heating machines.
The photo shows an automobile engine crankshaft
induction hardening machine.
In the front right is the hardening machine,
to the left is the cooling water tank and quenching water tank,
in the center is the incoming panel,
and to the right is the transistorized converter.
The hardening machine has been designed to optimize compactness
and the overall layout was designed to meet our customer's specifications.
This machine is installed in an engine production line,
where it receives the workpiece from the previous process,
and automatically sends it to the next process after hardening.
The photo shows an automobile engine crankshaft induction
hardening machine.
This machine is designed for fillet hardening of pins and journals of
compact, lightweight crankshafts.
This machine is installed in an engine production line,
where it receives the workpiece from the previous process,
and automatically sends it to the next process after hardening.
The workpiece is loaded from the left, then the pins are hardened
at the left hand station.
The journals are then hardened at the righthand station,
before the workpiece is unloaded to the right.
This machine is specified for compactness and short cycle time
(under 60 sec/pc).
This was achieved by designing and manufacturing coils to control
the high power at the fillet corners using the Elotherm method.
☆ In the Elotherm method, semi-open coils track the rotating workpieces,
achieving low distortion and even casing.
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.

The photo shows a track powertrain axle pipe induction hardening
and reheating machine.
※At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.
The pipe shaped workpiece is orientated horizontally in the hardening station.
This machine is able to treat pipes of various diameter and length
by retooling the machine.
This machine was designed for manual loading/unloading due to
the small lot size of truck axle shafts and the need to treat workpieces
of different specifications.
The green colored unit above the workpiece is the heating coil,
and the gold colored unit under the workpiece is the quenching jacket.
After the workpiece is loaded, the receive jig carries it down,
where it is held by the centering unit.
It is then lifted up, where model identification is done.
The workpiece is then carried under the appropriate coil for the workpiece model
and the coil is lowered onto the workpiece.
The workpiece is rotated while hardened.
Due to the large size of the workpiece, heating and quenching takes a
relatively longer time, but this hardening and reheating machine is able
to achieve a cycle time of 2 minutes per workpiece.
The photo shows the annealing station of our autmobile pinion shaft
induction annealing machine.
After the entire surface is hardened by carburizing, only the tip section
is annealed by induction. In particular, this machine anneals the workpiece
from the tip to the spline section.
Using our original semi-open coil, the workpiece is heated evenly along
its multi-diameter shape.

The product is the round component in the center of the image. The lower three-fifths of the vertical section is shaped into four blades, with their tips evenly and tightly pressed together.
To ensure the four blade tips are securely in contact, various techniques are applied, such as surface pressing around the blades and shaping them into a perfect circular form. The biggest challenge in the curling process is preventing twisting and eccentricity, as the connecting section to the carrier is only 0.3 mm wide and the pre-curling developed length is just 3 mm.
