Abstract

The invention discloses a precise high-efficiency polishing method and a precise high-efficiency polishing device for curved surface parts. The method comprises the following steps of: making numerous porous microspheres adsorbed with abrasive grains suspended in polishing solution; arranging a workpiece to be polished on a workpiece clamping device, immersing the workpiece to be polished in the polishing solution in a polishing tank, and rotating the workpiece clamping device to drive the workpiece to be polished to move under the action of a driving force; and starting an ultrasonic generator positioned at the bottom of the polishing solution and polishing the workpiece to be polished under the combined action of an ultrasonic exciting acting force and a viscous force of the polishing solution. The precise high-efficiency polishing device for the curved surface parts is characterized in that: the polishing solution is accommodated in the polishing tank; the porous microspheres are adsorbed with the abrasive grains; the upper part of the polishing tank is provided with the rotatable clamping device for clamping the workpiece to be polished; and the bottom of the polishing tank isprovided with the ultrasonic generator. The processing accuracy and processing efficiency are high by adopting the method and the device; and the method and the device have the advantages of simple structure of processing equipment and low cost.
