The material transfer mechanism 400 grasps the front of the material and transfers the material one by one to the placement position 221. In this process, no manual material transfer or discharge is required. At the same time, by driving the protective cover assembly to cover or move away from the material tray 131 by the driving assembly, the material tray 131 can be protected from being contaminated by debris or oil residue on the CNC machine tool. The automatic feeding method can reduce the consumption of manpower and improve production efficiency.
