As shown in fig. 1, a conventional polishing pad for numerical control polishing includes a polishing rod 1, a rod pin 2, and a polishing pad 5. The polishing rod 1 is used for connecting a numerical control polishing actuating mechanism and a polishing disc 5, and the rod pin 2 is matched with a pin groove on the polishing disc 5 to transmit the rotation torque generated by the polishing actuating mechanism to the polishing disc 5, so that the polishing disc 5 can rotate on a processed workpiece at a stable and adjustable rotation speed under the driving of the polishing actuating mechanism. After a round of polishing is finished, the numerical control polishing executing mechanism needs to lift the polished rod 1, but the risk of taking up the polishing disc 5 exists when the polishing rod starts to lift, namely, the polishing disc 5 is taken up by the polishing executing mechanism by a certain height and then falls on a processed workpiece, so that the problem of workpiece surface and even overall damage is caused, the processing time is prolonged invisibly, the production efficiency is reduced, and the risk is promoted.
