The invention relates to the field of industrial machining, in particular to an intelligent machining production line which comprises an unqualified product frame, a raw material preparation room, a finished product warehouse and a general control system component. The intelligent machining production line further comprises an AGV intelligent trolley distribution unit, a turning processing unit, amilling processing unit, a grinding processing unit, a thread rolling processing unit and a semi-finished product temporary storage unit; and the machining types are classified to form four independent processing units respectively, the processing units are controlled through the general control system component, and the process switching of each production task is completed by guiding an AGV intelligent trolley through instructions of the general control system component. The AGV intelligent trolley serves as a transmission chain on a traditional production line, and finally the AGV intelligent trolley distribution unit and the semi-finished product temporary storage unit form the soft connection of the whole intelligent production line, so that the connection of the processing units isrealized, the processing of each production task is completed, the labor loss is reduced, and the production efficiency is improved.
