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. What is gratifying is that domestic hardware measuring instrument manufacturers have increased their investment in the development of digital display technology and digital display products in recent years, and have achieved great results. The continuous improvement of the waterproof and dustproof performance (from IP54 to IP65, which can now reach IP67) also enhances the market competitiveness of domestic digital display measuring tools. In the past 10 years, China's hardware measuring tools have 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 2m CNC gear measuring instrument in China and is the most competitive in China. Precision measuring instruments.
Relevant statistics show that 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. After several decades of construction and development, China's hardware measuring industry has initially formed an industrial system with relatively complete product categories, a certain production scale and development capabilities, and has become the second largest hardware measuring tool producer in the world except Japan. 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 metal measuring instruments to calibrate and measure. 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. Domestic metal measuring tools have bright spots. From visual measurement to simple measurement to precision measurement, advances in measurement technology to a certain extent ensure the advancement of manufacturing technology.
Some are in the process (for example, the tool setting tool); others are detected afterwards (such as gear measuring instruments). 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 metal measuring instruments to calibrate and measure. According to industry experts, taking the wind power industry as an example, it represents and reflects the latest achievements and levels of advanced cutting technology and CNC cutting tools, digital measurement technologies and measuring instruments in a country to a certain extent. Some typical key components of power generation equipment such as turbine blades The machining and testing of typical parts such as rotor hubs and turbine rotor rotor inserts have received considerable attention from the tool manufacturing industry. 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.
The director of the National Precision Tools Engineering Research Center and director of the Chengdu Tool Research Institute stated that so far, the Center's achievements in the areas of new tool materials, tool material surface modification technologies, and gear meters 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 realize leap-forward development in terms of research and development, technological equipment and industrialization capabilities. The results have reached or reached the world advanced level. The successful development has changed China's long-term reliance on imports in this field. The person in charge 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 that of similar foreign products. At the international level, this instrument can compete with similar products in the United Kingdom and the United States. 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.
The measuring instrument plays a decisive role. During the debugging of the precision instrument of the National Precision Tool Engineering Research Center, the staff taps the button, and the automotive gear fixed on a detection platform quickly turns up. On the computer screen next to it, the numbers jump 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.
