The invention relates to an automatic production line for a high-precision grinding wheel. The automatic production line comprises a grinding wheel forming die and further comprises a lower mesh containing system, a feeding system, a charging system, a material scraping system, an upper mesh containing system, a mesh pressing system, a core ring containing system, a die pressing machine and a demoulding device, all of which are arranged on a production track. The grinding wheel forming die is arranged on the production track and conveyed, and lower mesh containing, feeding, charging, flat material scraping, upper mesh containing, mesh pressing flattening, core ring containing, die pressing forming and demoulding are sequentially finished. The automatic production line is high in automationdegree, feeding is convenient, charging is stable and uniform, meshes are flatly placed, raw materials in the die are uniform, and the grinding wheel die pressing forming quality can be better improved.
