Problems solved by technology

However, for a piece to be polished with a non-circumferential surface, such as the middle frame of a mobile phone, the surface to be polished is a rectangular peripheral surface surrounded by four rectangular surfaces. After direct fine polishing by a fluid polishing machine, the degree of polishing is not uniform, which is easy It appears that only a part of the polished surface meets the fine polishing standard
Although the polishing uniformity between each surface can be achieved by continuously adjusting the position of the workpiece to be polished, the production efficiency of this method is low

Embodiment 1

[0106] The polishing fixture that embodiment 1 adopts is as figure 1 Shown, the precise polishing method of embodiment 1 comprises the following steps:

[0107] The 20 pieces to be polished were randomly divided into two groups, among which: the 20 pieces to be polished were the middle frames of mobile phones after intermediate polishing, and the materials were all 6 series aluminum alloys, and the outer surfaces of each piece to be polished were left behind after intermediate polishing. Slight scratches under the surface, the scratch depth is about 0.001mm, no mirror effect, one of the parts of the outer surface of the piece to be polished is as Figure 7 shown. The two groups of pieces to be polished are subjected to fine polishing according to the following operations:

[0108] (1) Space and fix 10 parts to be polished between the first fixing part and the second fixing part with a partition, wherein the side of the middle frame of the mobile phone is close to the column,...

Embodiment 2

[0113] The polishing fixture that embodiment 2 adopts is identical with embodiment 1, and the polishing method of embodiment 2 is also roughly the same as the polishing method of embodiment 1, and its difference is that the fine polishing additive in the abrasive material of embodiment 2 is made of 7 parts Composed of tea seed oil, 45 parts of fine polish, 12 parts of brightener and 36 parts of boiling water.

[0114] After calculation, the yield rate of fine polishing by the method of Example 2 is 85%.

Embodiment 3

[0116] The polishing fixture that embodiment 3 adopts is identical with embodiment 1, and the polishing method of embodiment 3 is also roughly the same as the polishing method of embodiment 1, and its difference is that the fine polishing additive in the abrasive material of embodiment 3 is made of 9 parts Composed of tea seed oil, 50 parts of fine polishing liquid, 12 parts of brightener and 29 parts of boiling water.

[0117] After calculation, the yield rate of fine polishing by the method of Example 3 is 90%.

Abstract

The invention relates to a fine polishing method, According to the fine polishing method, a to-be-polished part with to-be-polished surfaces which are non-circumferential surfaces is fixed to a fixingmechanism of a polishing jig, and the surfaces needing to increase the grinding amount, of the to-be-polished part, are close to upright posts, so that the difference of grinding degrees between different surfaces is reduced, Therefore, all the polished surfaces, being non-circumferential surfaces, of the to-be-polished part are subjected to uniform friction resistance, small grinding degree difference and uniform polishing in the polishing process, so that the production yield is increased.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a fine polishing method. Background technique [0002] With the improvement of people's living standards, electronic products (such as mobile phones and notebook computers) have become an indispensable part of people's material life, and electronic products containing metal structural parts are favored by consumers because of their unique metal texture. [0003] Generally, metal structural parts are formed by metal forging or stamping. However, the surface of metal structural parts formed by forging or stamping often has defects visible to the naked eye such as burrs, scratches, and sand holes, and does not have a bright metallic luster or mirror effect. . Therefore, it is generally necessary to polish the surface of the metal structure after it is formed. [0004] Polishing generally includes rough polishing, medium polishing and fine polishing. Rough polishing, intermediat...
