Domestic hardware measuring spot bright

In the precision instrument debugging room of the National Precision Tools Engineering Research Center, the staff tapped the button, and the car gear fixed on a detection platform quickly turned up. On the computer screen next to it, the numbers leaped quickly. In just over 10 seconds, the measurement results are displayed, along with measurement values ​​and allowable deviation values, making it clear at a glance.

The deputy chief engineer of this research center, Gang Gang, commented on this self-developed rapid detection and sorting machine: Due to its high detection speed, high degree of automation, and low price, it meets the need for manufacturers to achieve 100% rapid detection of gears. Ensure the quality of the national car safety. The device fills the gap in the field of on-line detection and sorting of domestic automotive gears.

Graphically metaphorically, CNC cutters are the teeth of CNC machine tools and precision measuring instruments are the eyes of CNC machine tools. They are mutually reinforcing, closely related to each other, and they are equipped and serviced to promote the development of numerical control manufacturing equipment, especially digital cutting technology. Chengdu Institute of Tool Research senior engineer, doctoral tutor such an analogy. As the basis of CNC cutting technology, China's tool manufacturing industry still has a big gap with foreign advanced level in terms of technical level and performance quality of measuring instruments. Relevant statistics show that after decades of construction and development, China's measuring tool industry has initially formed an industrial system with relatively complete product categories, a certain production scale and development capability, and has become the world's second-largest producer nation with Japan.

Domestic metal measuring tools have bright spots. From visual measurement to simple measurement to precision measurement, advances in measurement technology have ensured advancements in manufacturing technology. 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 precision 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. According to industry experts, taking the wind power industry as an example, the machining and testing of typical components such as steam turbine blades, rotor wheel slots, and turbine rotor rotor slots in power generation equipment have been represented and reflected to some extent. The state-of-the-art cutting technology and the latest achievements and levels of CNC tooling, 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 the 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 gauges. 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, and now only the 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**, detection resolution of 0.02 microns, detection length of up to 20 meters. The price is much lower than that of 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 Tools 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 precision tool production equipment with independent intellectual property rights in China 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.
