Quality is more than making a good product!

· Constant temperature and humidity metrology room

The bearing manufacturing requires high processing accuracy requirements in the mechanical manufacturing industry. The metal materials used have characteristics of thermal expansion and cold shrinkage. The processing accuracy is greatly affected by the temperature change. The error caused by the temperature influence in the measurement is called temperature error. For the whole measurement system, also called the system error, is an important factor in the length measurement. The constant temperature and humidity metrology room adopts the HAIRF constant temperature and humidity machine. The temperature is controlled at 20 ℃± 1 ℃, and the humidity is controlled at 40% - 50%. The impact of the ambient temperature on the measurement results is minimized, so that is effective assurance for Hanking precision bearing becomes a world-class product.

· Advanced metrology instruments

The TRIMOS HPD1500s length measuring machine produced in Switzerland is for length measurement.
The profile shape will use SURFCOM 1910SD3-24 roughness profilometer produced by Tokyo precision and VMA4030 video measuring instrument produced by Suzhou Tianzhun precision instrument.
The cylindricity measurement will use TALYROND565 cylindricity meter produced by the British Taylor company.
In the future, large-size components will be measured by Zeiss three coordinates system.
