On the premise of intelligent manufacturing, the process model of intelligent shaft material processing was designed on the premise of intelligent manufacturing. On the basis of the combination of the dual power intelligent lathe, the integrated industrial control machine was centrally coordinated the machine tool combination, the truss robot and the joint robot, and the automatic up and down feeding system was used to make up an intelligent automatic spindle processing unit. The automatic processing unit had dual protection function of hardware and software. It has strong detection, monitoring and running function, and brings the digital communication system to the intelligent digital workshop management system.
