Abstract: This paper studies a new mechanical polishing technique for diamond self-supporting films prepared by polishing plasma sputtering CVD. The experiment explored the effects of the rotating disk speed, the size of the diamond powder particles, and the surface shape of the grinding disk on the grinding and polishing rate of the diamond self-supporting film. The research shows that the grooved disk has obvious rough grinding effect on the diamond self-supporting film, and the rate is higher. The flat disk is beneficial to improve the surface roughness of the diamond self-supporting film; The rotation speed of the cutting capacity. At this rotation speed, the grinding and polishing rate of the diamond self-supporting film is about 12 μm / h. In this paper, through the exploration of new process parameters, it provides strong technical support for the subsequent processing of diamond self-supporting film.

TV Stand, also known as TV cabinet. TV cabinets are mainly used to place TVs. With the improvement of people's living standards, electrical equipment matching TVs has appeared accordingly, resulting in the development of TV cabinets from single to diversified use, no longer a single use for placing TVs , but the collection and placement of TVs, set-top boxes, DVDs, audio equipment, discs and other products.
