The four diffraction grating ruling engines developed in Changchun Institute of Optics and Fine Mechanics are described. The design of the 1st engine started in 1958. The 1st and 2nd engines are mechanical engines. They were built up at 1959 and 1965 respectively. The 3rd and 4th engines are photoelectrically controlled engines. They were built up in 1970 and 1975 respectively. Each engine has its special constructional features. The 4th engine has phase look error of about 1/100 fringe in average in the ca...
