China still has gaps in the technical level of measuring instruments

In the careful instrument commissioning of the State Prudential Tool Engineering Research Center, the loved ones tapped the buttons and the car gears on a test platform were quickly and smoothly popping up. On the screen next to the computer, the numbers leaped quickly. In just 10 seconds, the measurement effect emerged, and there are measurement values ​​and promised short-sighted values ​​next to it. The deputy chief engineer of the research center Yu Gang just commented on the self-developed LeCheng rapid inspection and sorting machine: “Because the detection speed is high, the automation level is high, and the price is low, we are satisfied with the 100% speed of the gears for automobile manufacturers. The testing ensures the safety of the nation’s automobiles, and this setup has filled the gaps in the domestic online testing of automobile gear and the scale of the players.

“For example, numerical control cutters are the teeth of CNC machine tools, and careful measurement of the instruments is the eyes of CNC machine tools. They promote each other, and are closely related to each other, and they are equipped and serviced, urging the development of several manufacturing equipment, especially digital cutting technology.” Chengdu Institute of Tool Research senior engineer, doctoral tutor Xie Huayi so played for example.

With regard to the emergence of statistics, China’s measuring equipment industry has been set up and developed through decades of development. It has begun to form a property system with complete product categories, a certain production scale, and a pioneering capability. It has become the world's second largest producer of measuring tools except Japan. . However, as the root of CNC cutting technology, China’s tool manufacturing industry still has a big gap with the level of foreign advanced talents in measuring the quality of the instrument's craftsmanship, such as gentle quality of function.

The highlights of the country's production have been measured from the visual inspection to the prudent measurement, and the advancement of the measurement technology has guaranteed the advancement of manufacturing technology. Qian Xuesen, a renowned scientist, once pointed out: “The information craftsmanship includes measuring techniques, computer skills, and communication skills. Measuring skill is the key to success.”

The China Machine Tool and Tool Industry Association puts reporters to the attention of reporters. Careful processing and manufacturing not only require the precision and stability of the machine tool, but also the precision of the tools and fixtures. It is also necessary to carefully measure and measure the gauges. "Some of them are in the process of machining (such as the tool setting tool); some are after-the-fact detection (such as gear measuring instruments)."

Industry experts confided that 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 generator rotor embedded slots in power generation equipment are represented on a certain level. It reflects the latest efficacy and level of a country's cutting-edge cutting technology and CNC cutting tools, digital measurement technology and measuring instruments, and is therefore highly concerned by the tool manufacturing industry.

It is encouraging to feel that the domestic measuring tool manufacturers have invested heavily in the development of digital display technology and digital display products in recent years, and have achieved great results.
