The invention discloses a coarse grain eliminating forging process for a high-performance aluminum alloy component. The coarse grain eliminating forging process comprises the steps of preheating, blank making, forging, quenching, edge cutting and aging treatment. Compared with the prior art, the technical scheme provided by the invention has the beneficial effects that compared with a traditional aluminum alloy forging process, the solid solution process is advanced and combined with the blank preheating process into one process, the blank is manufactured in a hot working mode, and the blank is quickly cooled in water after hot die forging so as to preserve a forging structure; the common coarse grain problem in the aluminum alloy component forging process is solved, meanwhile, the solid solution heat treatment process after forging is omitted, the use of a solid solution furnace is saved, the production efficiency is improved, the purpose of optimizing energy consumption is achieved, meanwhile, water cooling
