    Abstract: 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.

    Abstract: A multi-fields assisted abrasive scouring polishing method and device. The device includes an abrasive pool, a heating device, an ultrasonic device, a peristaltic pump and a clamping table. In use, first, magnetic poles are installed on a longitudinal rod of a workbench, and the internal channel of the workpiece is communicated with the pump inlet hose. Second, polishing slurry and abrasive particles are added into the abrasive pool, the heating end of the heating device and the vibrating end of the ultrasonic device are immersed into the polishing slurry, and the heating device and the ultrasonic device are started. Finally, a magnetic field device is energized and magnetized, and the peristaltic pump is started to polish the internal channel. The device solves the problems of poor surface quality and low polishing efficiency of a complex long and thin internal channel in a machine part containing an internal channel.
