The paper investigates the annular lapping process of large-aperture reflective component. A 610 mm440 mm85 mm reflective component was processed by a lapping machine with a 4 m-diameter lapping disk. In order to improve the surface flatness of the optical component， the rotating speeds and locations of the conditioner and the workpiece ring，and the groove shape on the asphalt plate were optimized. The surface flatness converse more efficiently, with the best value of /6(=632.8 nm), after optimization. Thus annular lapping is suitable for processing large-aperture optical components.
