High end scientific instruments are the backbone of precision Engineering across many industries. these equipment hide behind the curtain but play indispensable role. China just unveiled high-precision roundness reference device for industrial Metrology.
According to a CCTV News report yesterday, China’s first high-precision roundness reference device has been officially completed.
According to reports, the device was developed by the National Institute of Metrology of China. Its completion marks a leapfrog development in my country's high-precision roundness measurement field, and its overall technical capabilities have entered the ranks of the world's advanced levels.
At the technical level, the device system integrates a number of independently developed technologies and has successfully overcome international technical bottlenecks such as high-accuracy roundness assessment, spindle error separation, and filter consistency control.
This device innovatively proposes a roundness calculation model based on high-accuracy roundness filtering and full-effect data utilization, effectively solving the stability problem of contour reconstruction after standard hemispherical separation. Simultaneously, my country's independently developed novel error separation technology significantly suppresses spindle rotation error, reducing roundness measurement uncertainty from 20 nanometers to 6 nanometers, achieving internationally advanced measurement capabilities. This breakthrough signifies that my country has achieved independent control over several core technologies for high-accuracy roundness measurement, breaking the long-standing foreign technological monopoly.
