The invention relates to an intelligent cutting and polishing production line for deep processing of glass and a deep processing method of glass. The production line comprises a bottom plate, an electric support slider, a support device, feeding support frames, an execution device and a support frame transverse plate, wherein the electric support slider is mounted in the middle of the bottom plate, the support device is mounted on the electric support slider, the feeding support frames are symmetrically mounted at left and right ends of the bottom plate and adopt an inverted U-shaped structure, the support frame transverse plate is arranged between inner walls of middles of the feeding support frames, and the execution device is mounted between the two feeding support frames. During working, the glass is conveyed onto the support device, the support device fixes the glass, then, the execution device cuts and edges the glass, manual operation is not required during processing, glass breakage caused by operation errors is avoided, the labor intensity of workers is reduced, the working efficiency is improved, and a cutting and edging procedure integrated continuous processing functionduring deep processing of the glass can be realized.
