The utility model relates to a numerically controlled milling machine multimedia teaching system, and pertains to the technical field of teaching tool product structures. The numerically controlled milling machine multimedia teaching system is characterized in that the numerically controlled milling machine multimedia teaching system comprises a host, the host is connected with a display screen and a control panel, the host is further connected with a numerically controlled milling machine used in the process of teaching, the numerically controlled milling machine comprises a machine tool basic part subsystem, a spindle box subsystem, a feeding servo system subsystem, a control system subsystem, a hydraulic system subsystem, a pneumatic system subsystem, a lubricating system subsystem, a cooling system subsystem and a chip removing and protection system subsystem. According to the utility model, the conventional separated teaching mode in which the theoretical study process is performed at first and then the practical operation process is performed can be overcome, the theoretical study process and the practical operation process are performed at the same time, the classroom is combined with the workshop, the teaching process is performed gradually according to the structure hierarchy of the milling machine, a three-dimensional animation demo mode is adopted, learners can conveniently understand and master the knowledge about the numerically controlled milling machine, the consciousness of innovation and the creative thinking of students can be facilitated, and the advantage of better teaching effect can be realized. According to the utility model, the subjective initiative of learners can be maximized, and the work can be performed creatively.
