The domestic hardware measure has bright spots continuously, from visual measurement to simple measurement to precision measurement, and the progress of measurement technology guarantees the progress of manufacturing technology to a certain extent. The scientist Mr. 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 precision, stability of machine tools and precision of tools and fixtures to ensure, but also require precision measuring instruments to calibrate and measure. Some are in the process of processing; Some are post-op tests. Precision machining and manufacturing not only require precision, stability of machine tools and precision of tools and fixtures to ensure, but also require precision measuring instruments to calibrate and measure. Industry expert Luobaihui said that in the wind power industry as an example, some typical key parts in power generation equipment such as turbine blades, rotor slots and turbine generator rotor slots, such as the processing and testing of typical parts, To a certain extent, it represents and reflects the latest achievements and levels of a country's advanced cutting technology and CNC tools, digital measurement technology and measurement instruments, and is therefore highly concerned by the tool manufacturing industry.

It is gratifying to note that the domestic hardware quantity instrument manufacturing enterprises have increased their investment in the independent development of digital display technology and digital hardware measurement equipment products in recent years, and have achieved great results. The domestic digital display has developed from the simple bar liquid crystal digital display to the more complex surface liquid crystal dynamic simulation image display in the past few years. The resolution of the digital card gauge grid has been developed from 0.01 mm to 0.001 mm, and the accuracy and reliability of the measurement have been significantly improved.. The continuous improvement of waterproof and dust protection performance also enhances the market competitiveness of domestic digital display devices. In the past 10 years, it has continuously strengthened its advantages in the development and manufacturing of precision instruments such as gear measuring instruments, surface roughness measuring instruments, and contour measuring instruments. It has successfully developed the largest domestic 2m CNC gear measuring instrument and has become the most competitive precision measuring instrument in China. manufacturer.

The dual-frequency laser interferometer is a core product independently developed by the center. At present, only the center has this technology and can produce this equipment. Its success has changed China's long-standing dependence on imports in the sector. Chao Gang proudly said: Many of the instrument's functions have broken the technical blockade of foreign countries. The detection resolution has reached 0.02 microns and the detection length can reach 20 meters. Prices are much lower than similar products in foreign countries, in the international, this instrument and the United States and other countries of similar products to determine the level! According to the director of the National Precision Tool Engineering Research Center and the director of the Chengdu Tool Research Institute, the center's achievements in new tool materials, surface modification techniques for tool materials, and gear gauges have so far been at the leading level in China. Through unremitting efforts, China now has the most advanced precision tools with its own intellectual property rights to produce equipment and has established an industrial base, which has enabled China's precision tools to achieve a leapfrog development in research and development, process equipment and industrial capabilities. Some of the results have come close to or reached advanced levels in the world.
