In recent years, with the further expansion of market awareness and the continuous improvement of business level, the business structure and product structure of decoration hardware in Hardware City have undergone profound changes.

Domestic hardware measuring tools continue to have bright spots, from visual inspection to simple measurement and then to precision measurement. The progress of measurement technology to some extent guarantees the progress of manufacturing technology. Famous scientist Qian Xuesen also pointed out that information technology includes measurement technology, computer technology and communication technology. Measurement technology is the key and foundation.

Precision machining and manufacturing not only require the accuracy and stability of machine tools, as well as the accuracy of cutting tools and fixtures, but also require precision measuring tools and instruments for calibration and measurement. Some are during the processing; Some are post hoc tests. Precision machining and manufacturing not only require the accuracy and stability of machine tools, as well as the accuracy of cutting tools and fixtures, but also require precision measuring tools and instruments for calibration and measurement.

Industry expert Luo Baihui revealed that, taking the wind power industry as an example, the processing and testing of some typical key components in power generation equipment, such as steam turbine blades, rotor wheel slots, and turbine generator rotor embedded wire slots, to some extent represents and reflects the new achievements and levels of a country's advanced cutting technology, CNC cutting tools, digital measurement technology, and measurement instruments, thus attracting the attention of the tool manufacturing industry.

It is gratifying that domestic hardware measuring tool manufacturing enterprises have increased investment in digital display technology and independent development of digital hardware measuring tool products in recent years, and have achieved tremendous results. Domestic digital display measuring tools have evolved from simple strip LCD digital displays in the past few years to more complex surface LCD dynamic simulation image displays. The resolution of the digital caliper capacitance grid has increased from 0.01 millimeters to 0.001 millimeters, and the measurement accuracy and reliability have been significantly improved.

The continuously improved waterproof and dustproof performance has also enhanced the market competitiveness of domestic digital measuring tools. In the past decade, we have continuously strengthened our advantages 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 current domestically produced * * large 2-meter CNC gear measuring instrument, becoming a competitive manufacturer of precision measuring instruments in China.

The dual frequency laser interferometer is the core product independently developed by the center, and now only the center in China has this technology and can produce this equipment. Its successful development has changed China's long-term dependence on imports in this field. Chao Gang proudly said that the multiple functions of this instrument have broken the technological blockade of foreign countries, with a detection resolution of 0.02 micrometers and a detection length of up to 20 meters. The price is much lower than similar foreign products, and internationally, this instrument can compete with similar products from countries such as the United States and the United States!

The director of the National Precision Tool Engineering Research Center and the director of Chengdu Tool Research Institute stated that so far, the center's achievements in new tool materials, tool material surface modification processes, gear measuring instruments, and other aspects have reached the domestic level. After unremitting efforts, we now have advanced precision tool production equipment with independent intellectual property rights in China, and have established industrialization bases. This has enabled China's precision tools to achieve leapfrog development in terms of research and development, process equipment, and industrialization capabilities, with some achievements approaching or reaching world advanced levels.

In addition to the above points, there are still many things to be done to enhance the comprehensive competitiveness of hardware enterprises. The task is heavy and the road is long. We hope that while pursuing profits, enterprises will not forget their social responsibilities. Only in this way can enterprises achieve sustainable and sustainable development.
