This paper studied how to improve the glass surface strength.The manufacture process in which the surface strength of glass changes was explored.According to the values of surface strength variation and the strength curves under different grinding processes, the reasons that the surface strength decreased and the related measures were given. Then, the etching method for releasing stress concentration and the max surface compressive stress strengthening theory were described, and the effects of different material removal modes on the surface strength of brittle materials were analyzed. A ductile grinding mode was introduced and its main manufacture requirements were given. The roughness ranges for different non-imaging surfaces were summarized, and corresponding solutions were advanced. The experiments show that as the material removal rate is set to be less than or equal to 25 μm/h and the abrasive size less than or equal to 15 μm, the polishing-similar surface will be achieved for several materials. The ductile grinding can induce an increase of the max surface compressive stress and avoid longitudinal micro-cracks which reduce the glass surface strength, so it is a reasonable grinding mode for glass surface strength improvement.
