The invention discloses a stainless steel highly-polished surface nondestructive grinding and roll finish repairing method. The method comprises the steps that A, CNC machining and CNC highly-polishedtreatment are conducted on a stainless steel product; B, grinding is conducted, specifically, the stainless steel product is placed in a roller of a centrifugal grinding machine, centrifugal grindingis conducted on the stainless steel product through a high-frequency ceramic grinding material, and the grinding time is 5-10 min; and C, roll finish is conducted, specifically, the ground stainlesssteel product is placed in a roller of a centrifugal roll finish mill, roll finish treatment is conducted with walnut sand as a grinding material, and the roll finish grinding time is 22-25 h. According to the method, as for the stainless steel highly-polished surface product needing to be machined and with the weight smaller than 30 g, the manufacturing procedures are reduced, the yield is increased, and the cost is reduced. By the adoption of the method, CNC machining is only needed once, the problem of damage to the highly-polished surface is solved through new technical schemes of grindingand roll finish, CNC secondary machining is reduced, cost is greatly saved, and the machining efficiency is improved.
