Lei Tianjue, male, Han nationality, is a native of Liuyang, Hunan Province. He graduated from the Institute of Technology of Peking University in 1935.
Lei acted as senior engineer of the Machine Science Research Institute of the China National Mechanic Industry Bureau. He has made significant contributions to such fields as precision measurement, precision processing, mechanic design and static pressure technique over the decades. He successfully developed tool grinders, inner circle grinders and boring lathes that achieved international recognition at the time.
Lei also developed centrifugal oil-fill type high-speed sliding bearings and angle-type lightwave interferometers, both of which have been applied to the design of grinders. He also studied phase regulation-type variable oil pumps, which were absorbed into production by foreign countries. Lei was responsible for the R & D of 1/10s index mechanisms, the precision of which was counted among similar instruments on the international level in the 1960s. In partnership with others, he was responsible for developing unique structure simple sidestep-type static pressure screw caps and static pressure-type bearings. He presided over the technical work of flexible wall spray tubes used in transonic tunnels, and developed elastic fluid static pressure bearings used for vibration test-bed activators.
Lei Tianjue was elected an academician of the Chinese Academy of Sciences in 1955.
