Numerical control machine tool

The invention relates to a numerical control machine tool which comprises a tool magazine used for storing tools. The protective door has a closed state for shielding the tool magazine and an open state for exposing the tool magazine; the machine head and the tool magazine are located on the two sides of the protective door respectively, and the machine head can get close to the protective door and take and place tools from the tool magazine in the open state; the first cleaning structure is arranged below the protective door in the vertical direction so as to receive and clean dirt; and the second cleaning structure is arranged above the protective door in the vertical direction and can clean the machine head in the process that the machine head gets close to the protective door. According to the numerical control machine tool, through joint cooperation of the protective door, the first cleaning structure and the second cleaning structure, dirt generated by workpiece machining, dirt attached to the machine h
