2.5 D / 3 D surface of glass, metal plate since its launch, by the industry, in order to guarantee the normal slip and has good iuster, usually need polishing treatment on the surface, surface polishing technology of glass and metal panel at present stage is to use glass polishing carpet, nylon brush with bristle brush or polishing liquid to use. But as a result of nylon brush bristle brush and brush the surface is smooth, when polishing, it is hard to drive the polishing liquid effectively polishing glass or metal surface. As a result, the production efficiency and rate is  low, the products listed in the process. Now also have to use white fiber leather polishing, also there are not effective to drive the polishing liquid for surface polishing, processing time, fast fine rate, low loss and high cost.
Beijing Century Sparks the surface of glass, metal pads, without changing the structure of the double sided lapping machine, fast polishing, 2.5 D mobile phone glass cover, for example:
A. 2.5 D glass wool embryo by CNC chamfering and cant after processing, the 9 um diamond thinning mat finishing 6-10 minutes, before throwing roughness;
B. using special fixture along under the cover plate edges (swimming star wheel thickness may be sheltered places) of polishing, double-sided machine of 970 plate size can polishing between 80-120 pieces at a time, with 2.5 D curved glass polishing disk takes 1500 seconds * 4 edges polishing is completed;
C. 0.3 0.5 mm swimming star wheel with the second step, 2.5 D glass wool embryo treated with 2.5 D curved glass special pads with dragon skin of polishing grinding of double-sided polishing at the same time, in 1500-1800 seconds to a plate of 2.5 D glass products, yield of 95%. D. inspection.
