On October 16th, the Coordinate Measuring Machine Technical Exchange Conference and the Third Discussion Conference on GB/T 16857.5 National Standard, organized by Shenzhen Zhongtu Instrument Co., Ltd., were successfully held in Shenzhen. The meeting brought together experts, scholars and enterprise representatives from the National Technical Committee for Standardization of Geometric Technical Specifications of Products, the Chinese Academy of Metrology, the Institute of Microelectronics of the Chinese Academy of Sciences, Hefei University of Technology, the National Future Measurement Laboratory of the United Kingdom, Shenzhen Zhongtu Instrument Co., Ltd. and other units in the field of coordinate measurement technology. The purpose of the meeting was to deeply discuss the new technology trends in the industry, and discuss the technical content of key national standards, so as to inject new momentum into the standardization and high-quality development of China's precision measurement technology.

Deepen standard discussions and solidify technical foundations

The agenda of the meeting is rich and in-depth. Experts, scholars, and business representatives in attendance had extensive exchanges on the cutting-edge technology of coordinate measuring machines, focusing on large-scale space laser tracking measurement technology and applications, coordinate measuring machine traceability technology for specific tasks, micro nano coordinate measuring machines, and other cutting-edge topics, bringing the latest research results and product introductions. Through the wonderful sharing of all the guests, we not only see the continuous improvement of the "precision" of technological development, but also the infinite possibilities of its application "breadth" and "depth".

Subsequently, the meeting entered the core stage - the third centralized discussion on the technical content of the national standard GB/T 16857.5 Product Geometry Technical Specification (GPS) Coordinate Measurement System (CMS) Acceptance and Re inspection Testing Part 5: Calibration Measuring Machine for Contact Detection Systems Using Single or Multiple Probes, Discrete Points, and/or Scanning Measurement Modes.

This standard is a crucial specification in the field of coordinate measuring machines (CMM), which specifies the acceptance and retesting methods for CMM using contact detection systems (including single probe, multi probe, discrete point, and scanning modes). With the rapid development of measurement technology, the application of multi probe and high-speed scanning technology is becoming increasingly widespread, which puts forward new requirements for existing standards. The attending experts engaged in lively and constructive discussions on key issues such as the technical details of the standard, the rigor of the testing process, and the adaptability to new technological models, laying a solid foundation for further improvement of the standard. This discussion has profound significance for unifying industry testing standards, ensuring the accuracy and reliability of coordinate measuring machines, and promoting the quality improvement of equipment manufacturing industry.

On site visits and exchanges, witnessing the strength of domestic production

In the afternoon of that day, the attending representatives moved to the Zhongtu Instrument Exhibition Hall for a visit and exchange. As a representative enterprise of domestically produced self-developed coordinate measuring machines, Zhongtu Instrument fully demonstrated its latest research and development achievements and manufacturing strength in the field of precision measurement to the attending guests. The core products displayed in the exhibition hall, such as high-performance coordinate measuring machines, laser trackers, non spherical detection profilometers, AI imagers, flash testers, white light interferometers, etc., have left a deep impression on visitors with their measurement accuracy, stable performance, and advanced software systems.

Through on-site observation and in-depth technical exchanges, the attending representatives personally experienced the breakthrough progress made by China in the field of coordinate measurement equipment. The independent research and innovation of Zhongtu Instrument in core technology demonstrates the strong competitiveness and enormous potential of "Made in China" in the field of precision measurement.

The technical exchange meeting and the discussion of national standards not only provided a platform for technical exchange and cooperation within the industry, but also enhanced the industry's confidence in the development of domestic coordinate measurement technology through on-site inspections. The improvement of standards and innovation in technology complement each other. The successful convening of this conference marks a solid step forward in China's standardization work and industrial self-reliance process in the field of coordinate measurement, which will effectively promote the continuous progress of China's manufacturing industry towards high quality and high precision.
