We provide evaluation test machines for research divisions of companies and apparatuses used in experiments and training at universities.
Test machines and inspection machines
Electric cart torque test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P1000796.jpg)
Torque test machine used in training at engineering and electrical engineering departments.
Rear wheel measuring section
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P1000796-2.jpg)
Small chassis platform is built on rear wheel and torque measurement for electric cart is performed.
Frictional wear test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_DSCF0082.jpg)
Surfaces of resins are coated with sample lubricant to measure frictional resistance under pressurized rotation.
Measuring section
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_DSCF0082-2.jpg)
Depending on the type of sample, frictional resistance under normal temperature and high temperature, or wear progression of resin is measured.
Low temperature torque test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/82-2_P3120063.jpg)
Grease performance below freezing temperature is measured.
Inside of measurement low temperature tank
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P3120063-2.jpg)
Grease resistance fluctuation within bearings set to jig is measured.
Bowden test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/82-2_B2.jpg)
Coefficient of friction of lubricant film on the surface of sample is measured.
Back and forth sliding motion measurement section
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_B2-2.jpg)
Test piece is pressurized on sample surface to repeat back and forth sliding motion from which the fluctuation in frictional resistance value is measured.
Shell-type four-ball extreme-pressure lubricant test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_shell.jpg)
Two types, instant extreme pressure (EP) and long duration light load (WEAR), can be measured.
Measuring container and test piece
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_shell-2.jpg)
The wear mark and load carrying capacity of the test piece is measured by putting the sample grease or lubricant in the 3 hard balls of the test piece and adding load and rotation from above with hard balls.
High temperature bearing test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P3120064.jpg)
Grease degradation with high temperature range is measured.
In-tank double-linked bearing set jig component
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P3120064-2.jpg)
10 pieces of bearings pressurized with jig is set to measure the status of grease degradation under high temperature and long duration.
Resonance experimentation jig
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_P1010585.jpg)
Sound or resonance data is collected by adjusting the width and thickness of the slit.
Assembly diagram

Design was based on the request of a professor of engineering/mechanical engineering department.
Single handle 4-axis rotational bending fatigue test machine (existing)
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_DSCF0096.jpg)
An old test machine installed in the material dynamics lab of an engineering department.
Single handle 4-axis rotational bending fatigue test machine (modified)
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_.jpg)
An existing test machine from the lab was overhauled.
Existing/test piece set component.
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_DSCF0097.jpg)
The existing test piece set component was a method of holding the test piece down from the outside with a set bolt, but the occasional loosening prevented stable data.
Modified/test piece set component
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_DSCF0097-2.jpg)
The spindle shaft was newly created to switch over to the collet chuck method.
As a result of switching the collet sleeve, test pieces with different diameter can be set.
Spark unit performance inspection apparatus
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_suprkunit.jpg)
Inspection line to perform continuous inspections of electrical current, voltage, and waveform of the spark unit all the way to packing.
Small back and forth sliding motion test machine
![](https://www.sukegawa-works.co.jp/wp-content/uploads/2-2_turntesut.jpg)
Measures, through back and forth sliding motion, the frictional resistance of the sample under light load.
