According to Dr. Tang Yuguo, executive deputy director of the National Raster Manufacturing and Application Engineering Technology Research Center, the new grating scoring machine has superior performance, with a maximum score of 400 mm × 500 mm and a maximum linear density of 6000 lines/mm. Level. The precision mechanical system will also include a multi-layer platform structure that fully complies with the "Abbe principle", a monolithic quartz tool holder guide that is load-bearing and guided, a continuous mid-way switching technique for diamond tools, and a combination of continuous operation and intermittent scoring. A number of innovations such as a unique way of working.
Speaking of the grating scriber known as the "king of precision machinery", many people feel unfamiliar and think that they are far from their own lives. In fact, the detection of large space, as small as the blood sugar test, will inevitably play a role in the grating, and the grating scriber is the working machine for manufacturing the grating.
Tang Yuguo said that grating is the core component of spectroscopy instruments. Only with the new grating technology can new spectroscopy instruments be promoted and the innovation and development of the entire spectroscopy industry be promoted. The development of large-scale high-precision diffraction grating scriber will greatly improve the level of grating manufacturing in China, promote the rapid development of the spectrum instrument industry and spectral testing technology, and enhance the independent innovation capability of China's precision machinery manufacturing industry.
It is understood that the project will be developed on the basis of China's long-term technology accumulation and breakthroughs in key technologies, relying on the Changchun Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences and relevant technical forces within the United Nations. At present, it has been supported by the national major scientific research equipment development project, with a total funding of 118 million yuan. In addition, the project has been included in the list of ten major scientific and technological projects in Jilin Province.
China's diffraction grating scoring machine project
Xinhuanet Changchun December 3 (Reporter Zongxi) The reporter learned from the Changchun Institute of Optics and Mechanics of the Chinese Academy of Sciences on the 2nd that China's high-precision diffraction grating scoring machine project has been implemented and is expected to be successfully developed in 2012.
