China’s First Ultra-precision Gear Technology
Changchun Institute of Optics, Fine Mechanics and Physics
Beginning in the 1960s, a research team from the Changchun Institute of Optics, Fine Mechanics and Physics, led by CAS member WANG Liding, dedicated about 40 years to the development of ultra-precision gears.
The team gradually improved the precision of the gears from grade 7 to grade 1, making China one of few countries with world-leading, ultra-precision gear technology.
