Cylindrical optical element is a common type of aspheric lens, which can realize the transmission, shaping and amplification of the beam in the optical system. It has a wide range of applications, such as linear detector illumination, holographic illumination, optical information processing, strong laser system and synchrotron radiation beamline. In this paper, an efficient robot-assisted rotation-revolution ultra-precision belt grinding technology was presented for cylindrical optical element. First, the structure of device and processing principle of the rotation-revolution belt grinding device was introduced. Then, based on the generalized Preston equation and Hertz contact theory, the removal function of the ultra-precision belt grinding was established. Finally, the cylindrical element of optical glass with a diameter of 50.09mm was ground. After 6 hours of processing, the cylindricity accuracy of the element was decreased from original 112.4μm to 4.6μm, and the surface roughness was decreased from 2.631μm to 3.085nm.
