Tsinghua university department of precision instruments and machinery was established in 1932, its predecessor was founded in 1932, tsinghua university college of engineering mechanics department, adjusted for the s department of tsinghua university machinery manufacturing system, the early s, and adjusted for precision instrument engineering and mechanics, and in the eighty s was renamed as today's department of precision instruments and machinery.

At present I have three people is academician, 1 foreign academician, "the Yangtze river project" distinguished professor 5 people, on-the-job professor 52, associate professor and doctoral degree, the 114 people.

In recent years, with microelectronics, computer, automatic control, laser and other new technology and modern mechanical design, modern manufacturing engineering, modern control and the development of the theory of information, I system continuously break through the traditional field, renew the teaching content, to adapt to the world the development of science and technology and national economic development needs, and gradually formed a machine, light, electricity, combined with the characteristics of interdisciplinary.

At present, the whole system with precision instrument and mechanical, optical engineering, mechanical design and theory and machinery manufacturing and its automation and so on four national key disciplines, in the national first
