The invention relates to the technical field of numerical control machine tools, in particular to a drainage mechanism which comprises a drainer, a liquid storage cavity and a vacuumizing channel are arranged in the drainer, the two ends of the vacuumizing channel penetrate through the two sides of the drainer respectively to form a first vacuum opening and a second vacuum opening respectively, and the liquid storage cavity is communicated with the vacuumizing channel. A first on-off valve for controlling the on-off of the vacuumizing channel is arranged at the position, corresponding to the second vacuum port, of the vacuumizing channel; one end of the drainage channel is communicated with the liquid storage cavity, and the other end of the drainage channel penetrates through the side face of the drainer to form a drainage opening. A second on-off valve used for controlling connection and disconnection of the drainage channel and the liquid storage cavity is arranged at the joint of one ...
