Bearing manufacturing is a machinery manufacturing industry in the processing precision requirements of the industry; the metal materials used have the characteristics of thermal expansion and contraction, processing accuracy is greatly affected by temperature changes, and the measurement of the temperature affected by the error is called the temperature error, for the entire measurement system, also known as the systematic error, is the length of the measurement of an essential factor. The temperature and humidity measurement room adopts HEFRI continuous temperature and humidity machine; the temperature is controlled at 20℃±1℃, and the humidity is maintained at 40%-50% to minimize the influence of ambient temperature on the measurement results.
The length measurement will use the Swiss production of TRIMOS HPD1500S length measuring machine; contour shape will use the Japan Tokyo Precision production of SURFCOM 1910SD3-24 roughness profiler, Suzhou Tianzhun precision instruments produced by the VMA4030 video measuring instrument; roundness measurement will use the British company Taylor's production of the TALYROND565 cylindricity instrument; the future of large-scale workpieces will be used in the German Zeiss coordinate to carry out measurements.
