Abstract

The invention relates to the technical field of metal surface polishing, in particular to a mirror polishing process for a super-hard mobile phone metal baseplate. The mirror polishing process comprises the following steps: S1, cleaning the super-hard mobile phone metal baseplate and fixing the cleaned super-hard mobile phone metal baseplate on a tooling fixture; S2, carrying out milling processing, that is, subjecting to the super-hard mobile phone metal baseplate to milling operation; S3, carrying out rough processing by adopting 1000-mesh alumina sandpaper; S4, carrying out degreasing, cleaning and air-drying; S5, grinding and polishing the super-hard mobile phone metal baseplate by utilizing a polisher, carrying out degreasing and cleaning by adopting ultrasonic waves again, and carrying out drying; and S6, carrying out waxing for protection. According to the mirror polishing process provided by the invention, the reasonable technological conditions are adopted; a milling processing and polisher cooperation method is utilized; the delivery glossiness is kept through waxing; the smoothness of the super-hard mobile phone metal baseplate is effectively improved; and the super-hardmetal surface roughness problem is solved.

Description

technical field [0001] The invention relates to the technical field of metal surface polishing, in particular to a mirror polishing process for a superhard mobile phone metal backplane. Background technique [0002] With the continuous progress of society and the continuous development of science and technology, people's quality of life is also rising. In daily life, portable electronic products are one of the necessities for people to go out, such as tablet computers and mobile phones. In order to improve the aesthetics of these electronic products, the shells of such electronic products are usually made into shells with mirror luster, but the existing shells with mirror luster are easy to be scratched, so some manufacturers use a super-hard Metal is used as the metal backplane of mobile phones, but superhard metals have high hardness, and the traditional mirror polishing method is poor. Therefore, we propose a mirror polishing process for superhard mobile phone metal backp...
