Are there obvious advantages in precision machining in Dongguan? When did the concept of precision machining technology start?

With the transformation and upgrading of China's economic structure, investment in high-tech research and development has gradually increased, and a large number of workshops and laboratories containing precision instruments or equipment have emerged. However, the vibration caused by urban construction and urban traffic has had an inevitable impact on building facilities and precision instruments, causing widespread concern in the construction industry. Vibration reduction and isolation technology is currently the main effective means of earthquake protection for precision instruments and equipment.

The domestic concept of ultra-precision machining technology was truly and systematically put forward from the 1980s to the early 1990s. Due to the development of aviation, aerospace and other military industries, higher requirements for machining accuracy and surface quality of parts were put forward. , These military industries have invested funds to support research institutes and universities in the industry to start basic research on ultra-precision processing technology. Since the ultra-precision processing technology at that time belonged to military technology, both in terms of equipment and technology, foreign countries implemented technical blockades, so the development of domestic ultra-precision processing technology basically started with the research of ultra-precision processing equipment. Ultra-precision processing technology also plays a big role. Artificial joints use titanium alloy or other precious metal materials. The surface treatment of these high-precision parts has extremely high requirements for cleanliness, smoothness and surface roughness, and ultra-precision research is required. The shape of tossing should be customized according to the individual's body structure. The price is expensive abroad, but there is a big gap in terms of service life and safety in China.
