The invention discloses an integrated production process of annular thin-walled powder products, and a production system thereof. The integrated production process comprises the major steps that a hydraulic press is adopted for product pressing molding; pressing-molded products are transferred; product milling is conducted through a drilling and milling machine; the milled products are transferred; and stacking is conducted. Automatic integration of pressing, milling and stacking of the products is achieved, the number of transferring and stacking times is decreased, repetitive work is eliminated, labor consumption is lowered, and the duration of the whole production process is greatly shortened; and meanwhile, the production system used for the production process can automatically conveyand mill the pressing-molded products, acting force is gentle during milling, the products are not prone to being damaged, the pressing-molded products do not need to be cured, while automatic millingand transferring of the products are achieved, the duration of the working procedure is shortened, the production efficiency is improved, the product pass rate is increased, and material waste is reduced.
