Along with the transformation and upgrading of China's economic structure, the investment in high-tech research and development has gradually increased, followed by the emergence of a large number of plants and laboratories containing precision instruments or equipment. However, the vibration caused by urban construction and urban traffic has an unavoidable impact on the building facilities and precision instruments, causing widespread concern in the construction industry. Vibration reduction and isolation technology is currently the main effective means of vibration protection for precision instruments and equipment.
The concept of ultra-precision machining technology was really put forward systematically in China from the 1980s to the early 1990s. As the development of military industries such as aviation and aerospace put forward higher requirements on the machining accuracy and surface quality of components, these military industries invested funds to support the research institutes and universities in the industry to start the basic research on ultra-precision machining technology. As the ultra-precision machining technology belonged to military technology at that time, foreign countries implemented technology embargo in terms of equipment or process, so the development of domestic ultra-precision machining technology basically started from the research of ultra-precision machining equipment. Ultra-precision machining technology also plays a big role, artificial joints using titanium alloy or other precious metal materials, the surface treatment of these high-precision parts have extremely high requirements for cleanliness, finish and surface roughness, the need for ultra-precision grinding and polishing, the shape should be customized according to the individual body structure, expensive abroad, while there is a large gap in terms of service life and safety in China.
