A three-dimensional precision motion sliding table for cutting machining according to claim 1, characterized in that the second driving assembly (B) comprises a second bevel gear set, a stop rod (B10) is vertically fixed at one end of the base (B9), and a third round wheel push rod (B8) is arranged on the side surface of the housing assembly in a penetrating manner; when the second bevel gear group is in transmission, the third round wheel push rod (B8) can be driven to reciprocate left and right relative to the stop rod (B10), so that the shell assembly can slide left and right relative to the base (B9).
8. The three-dimensional precision motion sliding table for cutting machining according to claim 7, wherein a second elastic member is sleeved on the third round wheel push rod (B8), the second elastic member is located between the shell assembly and the stop rod (B10), and the second elastic member is used for providing a pretightening force to enable the stop rod (B10) and the shell assembly to be far away from each other in the left-right direction.
9. A three-dimensional precision motion slide for cutting machining according to claim 1, characterized in that the machining platform comprises an ultrasonic micro-motion platform (C) and a workpiece mounting plate (E) which are integrally arranged from bottom to top, wherein the workpiece mounting plate (E) is used for placing the workpiece to be machined, and the ultrasonic micro-motion platform (C) is used for providing a high-frequency vibration field for the workpiece to be machined so as to reduce average cutting force in the machining process.
10. A three-dimensional precision motion slide for cutting machining according to claim 1, characterized in that the base (B9) is provided with a slide rail, and the lower surface of the housing assembly is provided with a slide groove cooperating with the slide rail.
