ABOUT

Solving challenges with customers

Based on our extensive measurement experience with the latest testing and measuring equipment,
we propose optimal measurement techniques and results to resolve challenges for our customers.

Three
NAS-conforming high-speed thread loosening testing machines

Compatible sizes range from M5 to M16 (as well as M4 and M18 to M36) according to the standard.
In addition, actual customer fastening bodies
can be mounted on the excitation table to apply vibration directly.
(There are weight restrictions)

Three
threaded fastener tightening testing machines

Compatible sizes range from M3 to M75.
These machines can clarify tightening characteristics
(torque coefficient, friction coefficient, yield tightening torque, axial force, etc.)
by measuring torque, axial force, and rotation angle.

We also carry various measuring instruments to measure the shape of any object.

Testing machines

Locking performance judgment

▶NAS Conforming High- Speed Thread Loosening Testing Machine

This machine is produced to conform to NAS3350 (U.S. National Aerospace Standard) tester specifications, and is used for judgement and comparison of locking performance.

▶Junker Type Thread Loosening Testing Machine

Used to verify the tightening force and vibration resistance of bolts and nuts.

Proof load test

▶Universal Testing Machine

Used for proof load tests that are satisfied by JIS B 1052-2 (Mechanical properties of fasteners made of carbon steel and alloy steel).

Threaded fastener tightening test

▶Threaded Fastener Tightening Characteristic Testing Machine

This machine conforms to JIS B 1084 (Fasteners-Torque/clamp force testing), and is used for measuring characteristic values resulting from tightening.

Locking performance judgment

▶Prevailing Torque Testing Machine

Measures prevailing torque (friction torque generated by the friction ring acting on the tip of the thread portion of the bolt). Measurement can be automatically repeated any number of times.

Measuring instruments

Shape measurement

▶Image measuring instrument

Fully automatic and highly accurate measurement is possible.

Made by KEYENCE CORPORATION

▶Microscope

Observation, photography, and measurement can be performed with ease.

Made by KEYENCE CORPORATION

▶Projector

Objects to be inspected can be measured with accurate magnification.

Made by Mitutoyo Corporation

▶Contracer
(contour measuring instrument)

Specialized for shape measurement and surface-roughness measurement.

Made by Mitutoyo Corporation

Hardness measurement

▶Rockwell hardness tester

Measures hardness, including heat-treatment condition and material identification.

Made by Akashi Seisakusho,Ltd.

▶Micro Vickers hardness tester

It can also measure the hardness of microscopic objects.

Made by Akashi Seisakusho,Ltd.

Film thickness measurement

▶Fluorescent X-ray coating thickness gauge

Film thickness measurement and material analysis equipment using fluorescent X-ray irradiated from above.

Made by FISCHER INSTRUMENTS K.K
