China Precision Hardware Tools

Domestic hardware measuring tools continue to have bright spots. From visual inspection to simple measurement to precision measurement, the progress of measurement technology guarantees the progress of manufacturing technology to a certain extent. Scientist Mr. Qian Xuesen also pointed out: Information technology includes measurement technology, computer technology and communication technology. Measurement technology is the key and foundation.

Precision machining not only requires the accuracy and stability of the machine tool and the accuracy of the tools and fixtures to ensure, but also requires precision measuring instruments for calibration and measurement. Some are in the process of processing; some are after the inspection. Precision machining not only requires the accuracy and stability of the machine tool and the accuracy of the tools and fixtures to ensure, but also requires precision measuring instruments for calibration and measurement. Industry expert Luo Baihui revealed that taking the wind power industry as an example, the processing and testing of some typical key components in power generation equipment, such as steam turbine blades, rotor grooves, and steam turbine generator rotor wiring grooves, represent and reflect to a certain extent. The latest achievements and levels of a country’s advanced cutting technology and CNC tools, digital measurement technology and measuring instruments have attracted the attention of the tool manufacturing industry.

It is gratifying that domestic hardware measuring instrument manufacturers have increased their investment in digital display technology and independent development of digital display hardware measuring products in recent years, and have achieved great results. Domestic digital measuring tools have developed from the simple bar-shaped LCD digital display in the past few years to the more complex surface-shaped liquid crystal dynamic analog image display. The resolution of the digital caliper's capacity grid has developed from 0.01 mm to 0.001 mm, and the measurement accuracy and reliability Both have improved significantly. The continuous improvement of waterproof and dustproof performance has also strengthened the market competitiveness of domestic digital display measuring tools. 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 profile measuring instruments. It has successfully developed the largest domestically made 2m cnc gear measuring instrument, which has become the most competitive precision in China Manufacturer of measuring instrument.

The dual-frequency laser interferometer is the core product independently developed by the center. At present, only the center has this technology and can produce this equipment in China. Its successful development has changed China's long-term dependence on imports in this field. Chao Gang proudly said: The multiple functions of this instrument have broken the foreign technical blockade, the detection resolution can reach 0.02 microns, and the detection length can reach 20 meters. The price is much lower than similar foreign products. Internationally, this instrument can compete with similar products in Britain, the United States and other countries! The director of the National Precision Tool Engineering Research Center and the director of Chengdu Tool Research Institute said that so far, the center's achievements in new tool materials, tool material surface modification technology, and gear measuring instruments have been at the leading domestic level. After unremitting efforts, we now have the most advanced precision tool production equipment with independent intellectual property rights in China, and established an industrialization base, enabling China's precision tools to achieve leapfrog development in terms of R&D, process equipment and industrialization capabilities. Some The results have approached or reached the world advanced level.
