WIPO Patent Application WO/2021/031478

A1

A uniform polishing device for crystal materials and use method thereof. The polishing device comprises: a feeding unit (1), a clamping unit (2), a polishing unit (3), and a control unit; the feeding unit (1) drives a workpiece to move along a determined motion trajectory on a surface of the polishing unit, and feedbacks information related to the motion trajectory to the control unit in real time; the clamping unit (2) clamps the workpiece and enables the workpiece to rotate during movement, and is used for providing a certain loading force for the workpiece; the polishing unit (3) polishes the workpiece moving on a surface thereof; the control unit controls the motion trajectory of the feeding unit (1), and controls the loading force of the clamping unit (2). The use method polishes the workpiece on the basis of the polishing device. The polishing device and the method can ensure the uniformity of the removal rate of a workpiece, and improve the geometric precision and surface quality of the workpiece.
