The invention relates to a numerical control milling machine with a cutting fluid recycling function. The numerical control milling machine comprises a base, a power device, a milling cutter, a bracket and a supporting mesh, and further comprises a circulation mechanism and a heat dissipation mechanism, wherein the circulation mechanism comprises a first communication pipe, a second communicationpipe, a purifying box, a filter screen, a guide plate, a power pump, a pipeline, two heat conduction pipes and two nozzles, and the heat dissipation mechanism comprises a first drive shaft, a second drive shaft, a first gear, a second gear, a friction disk and two fan blades. According to the numerical control milling machine with the cutting fluid recycling function, by means of the circulation mechanism, the cutting fluid can be recovered, recycling of the cutting fluid is realized, and production cost of the numerical control milling machine is reduced; and by means of the heat dissipationmechanism, temperature of the cutting fluid is reduced, lubricating effect of the cutting fluid is improved, and working reliability of the numerical control milling machine is improved.
