    摘要: A double-sided polishing method for an optical lens belongs to the technical field of ultra-precision machining. In the double-sided polishing method, upper and lower surfaces of the lens are polished simultaneously by arranging abrasive tools on upper and lower positions of the lens, making the abrasive tools close to the upper and lower surfaces of the lens to swing back and forth in the polishing process, producing relative motion and removing the surface materials. In the present invention, in order to eliminate a problem of removal ununiformity, a method for swing machining of abrasive tools and methods for turning over and polishing of workpieces are adopted in a polishing process, which can realize the high efficiency double-sided high-precision machining for a nonplanar lens, and the method can be applied to the double-sided polishing for different types of lenses.
