The breakthrough of China's ultra-precision gear level 1 precision is a typical representative of solving this precision problem, and it is also a typical case of my country's independent mastery of key technologies. Western developed countries have imposed a technological blockade on China. In order to independently master core technologies, Wang Liding, an academician of the Chinese Academy of Sciences, has spent more than 40 years and led his team to successfully develop ultra-precision standard gears with level 1 precision in the international standard for gears since 1999.
