Brake hub automatic machining system and using method thereof

The invention provides a brake hub automatic machining system. The brake hub automatic machining system comprises a first feeding bin, a first vertical machining center, a first turning-milling composite center and an overturning cleaning center which are transversely arranged side by side, wherein a transverse supporting assembly is arranged above the first feeding bin, a transverse sliding railis fixedly connected to the upper portion of the supporting assembly in the length direction of the supporting assembly, and the transverse sliding rail is connected with a movable material taking device which can move back and forth along the sliding rail and is used for automatically clamping brake hubs and transferring the brake hubs in sequence. Through the first feeding bin, the first vertical machining center, the first turning-milling composite center, the overturning cleaning center, a second turning-milling composite center, a second vertical machining center and a second feeding binwhich are arranged side by
