The invention discloses a control system of a general two-dimensional numerical control spinning lathe. The system comprises a processing operation layer, a control equipment layer and a lathe equipment layer, wherein the processing operation layer is connected with the control equipment layer, the control equipment layer is connected with the lathe equipment layer, the processing operation layer consists of a control panel, a data keyboard and a human-machine operation interface of an upper computer, the control equipment layer consists of a movement control system and a frequency changer of a lathe main shaft motor, and the lathe equipment layer consists of a signal detection mechanism and an electromechanical executing mechanism arranged on the spinning lathe. Compared with the prior art, the control system has the advantages that the full automation of the feeding, processing and discharging processes of workpieces is realized, the hardware equipment connection is simple, and the manufacture cost of the equipment is low. The system is particularly suitable for being used for processing small-batch spinning products with uncertain workpiece sizes.
