For support micro, dial gauge
used in end-measuring machine, electronic micrometer, we use
products made by the German Mahr company.
The Johansson 00 grade gauge block is NSS measurement dimension
accuracy default.
From Johansson gauge block, gauge block for the inspection
room and gauge block for use on the factory area make up our
calibration system. |

NN taper bearing pressure
management is a difficult task.
At NSS, we use Special gauge for accurate pressure management.

Our roundness measuring machine
is a Taylor Hobson Talyrond.
0.1micrometer measurement is possible. |

At NSS, we also manufacture taper
gauges.
Using our gauge manufacturing technology, we perform spindle
taper processing.
We use blue gel Paste for measurement of contact impact with
taper gauge. |

| Movement balance adjustment |
|
When a rotating solid is dynamically
disproportional, for example in a washing machine, if bias
exists in the dewatering bin, intensive vibration and noise
is generated.
At NSS, we take every step to eradicate disproportion in all
processes.
At the design stage, we verify the concentricity of internal
and external diameters at the lathe machining process, the
spreading of spline, cut hole, tap etc, and depth accuracy,
bending after heat treatment, etc.... For grinding operation,
not only the bearing joint part, but also we as much as possible
make effort to grind parts that are not directly related to
accuracy like the mill scale edge, C surface, key part, internal
diameter, bolt holes, etc.
If after that, there still remains disproportion, it is
possible to use a disproportion testing equipment to
adjust it to below 0.01ｇ.
After that, the product is assembled and final balance
adjustment is performed using Schenck vibropot to accurately
adjust all rotating areas.
Same as for grinding machine's grinding wheel movement
balance. Auto balancer and other equipment are used to eliminate
disproportion. |
