Embodiment 1

[0044] A. CNC, CNC processing and CNC high-gloss treatment for stainless steel products.

[0045] B. Grinding. Place stainless steel products in the drum of a centrifugal grinder, and use high-frequency porcelain abrasives to perform centrifugal grinding on stainless steel products. The grinding and rotating mode of the drum of the centrifugal grinder includes rotation around the central axis of the drum and centrifugal grinding. The type grinding machine revolves for the shaft, which greatly improves the grinding efficiency and effectively removes the burrs on the product surface. The rotational speed of the drum of the centrifugal mill was 50 Hz. Grinding time is 5min; single production capacity is 100pcs / barrel.

Abstract

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.

Description

technical field [0001] The invention relates to the processing field of stainless steel appearance products, in particular to a non-destructive grinding and rolling repair method for high-gloss stainless steel surfaces. Background technique [0002] The high-gloss surface is usually used for exterior decoration of metal products, which makes the product look dazzling and can increase consumers' acceptance of the product. For example: the high-gloss surface on the camera circle of the mobile phone, the bright edge of the whole circle of the back cover of the mobile phone, etc. [0003] The high-gloss surface is extremely non-wear-resistant and scratch-resistant before surface protection, and is easy to be damaged. Iron filings, grinding, sandblasting and other processes during cutting will cause varying degrees of damage to the high-gloss surface, which limits the high-gloss processing technology. Such as figure 1 As shown, in the prior art, high-gloss surface processing is...
