Hardware industry to increase development investment has achieved great results
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.
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 the research center Yu Gang just commented on this self-developed rapid detection sorter: “Because of the high detection speed, high degree of automation, and low price, it has met the needs of auto manufacturers to achieve 100% rapid detection of gears. This guarantees the quality and safety of the national automobile. The equipment fills the gap in the domestic automotive gear online detection and sorting technology field."
"Imagery metaphor, CNC tool is the teeth of CNC machine tools, precision measurement instruments are the eyes of CNC machine tools. They are mutually reinforcing, closely related to equipment, services, and promote the development of CNC manufacturing equipment, especially digital cutting technology." Chengdu tool research The equivalent of the senior engineer and doctoral tutor Xie Huayu.
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.
From visual inspection to simple measurement to precision measurement, advances in measurement technology have ensured advancements in manufacturing technology to some extent. 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 foundation."
The person in charge of the China Machine Tool Industry Association told the author that 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. "Some of them are in the process (such as the tool setting); some are after the test (such as gear measuring instruments)."
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 domestic measuring tool manufacturers have invested heavily in the development of digital display technology and digital display products in recent years and have achieved tremendous 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 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.
