China's precision machining, manufacturing and measurement technologies are close to world standards

In recent years, with the further expansion of market awareness and the continuous improvement of business grades, domestic hardware measuring tools have continued to shine brightly. From visual inspection to simple measurement to precision measurement, advances in measurement technology have ensured progress in manufacturing technology to some extent. The famous scientist Mr. Qian Xuesen also pointed out: Information technology includes measurement technology, computer technology and communication technology. Measurement technology is the key and the foundation.

Precision Machining requires not only the precision and stability of the machine tool, but also the accuracy of the tools and fixtures. It also requires precision measuring instruments to calibrate and measure. Some are in the process of processing; others are detected afterwards. Precision machining requires not only the precision and stability of the machine tool, but also the accuracy of the tools and fixtures. It also requires precision measuring instruments to calibrate and measure. Industry expert Luo Baihui disclosed that taking the wind power industry as an example, the machining and testing of typical components such as turbine blades, rotor wheel slots, and turbine generator rotor embedded slots in power generation equipment are represented and reflected to some extent. The state-of-the-art cutting technology and the latest achievements and levels of CNC cutting tools, digital measurement technology and measuring instruments have attracted the attention of the tool manufacturing industry.

It is gratifying that the domestic hardware measuring instrument manufacturers have increased their investment in digital display technology and digital display hardware product development in recent years, and have achieved great results. Domestic digital display tools have evolved from the simple bar LCD digital display of previous years to the more complex image display of surface dynamic liquid crystal dynamic simulation. The resolution of the digital video scale grid has been developed from 0.01 millimeter to 0.001 millimeter, and the accuracy and reliability of measurement have been improved. Have a significant increase. The continuous improvement of waterproof and dustproof performance also enhances the market competitiveness of domestic digital display devices. In the past 10 years, we have continuously strengthened our strengths in the development and manufacturing of precision instruments such as gear measuring instruments, surface roughness measuring instruments and contour measuring instruments. We have successfully developed the largest 2m CNC gear measuring instrument in China and become the most competitive precision in China. Measuring instrument manufacturer.

The dual-frequency laser interferometer is a core product independently developed by the center. Now only this center has the technology to produce this equipment. Its successful development has changed China's long-term dependence on imports in this field. He just said proudly: The instrument's many functions have broken the foreign technology blockade, detection resolution of 0.02 microns, detection length of up to 20 meters. The price is much lower than similar foreign products. In the international arena, this instrument can compete with similar products in countries such as Britain and the United States. The director of the National Precision Tool Engineering Research Center and director of the Chengdu Tool Research Institute stated that so far, the center is The results of new types of tool materials, surface modification technologies for tool materials, gear meters, etc. have been at the leading level in the country. Through unremitting efforts, it has now possessed the most advanced production equipment for precision tools with independent intellectual property rights and established an industrialization base, which has enabled China's precision tools to achieve leap-forward development in terms of research and development, technological equipment and industrialization capabilities. The results have reached or reached the world advanced level.

To enhance the comprehensive competitiveness of hardware companies, in addition to the above points, there are still many things to do. We have a long way to go, and we hope that companies will not lose sight of their social responsibilities while pursuing profits. Only in this way can a business get a lasting and sustainable development.
