The invention relates to a numerical control drilling machine with a cooling liquid recycling and scrap cleaning function. The numerical control drilling machine comprises a base, a bracket, a power device and a drill and also comprises a scrap removal mechanism and a circulation mechanism, wherein the scrap removal mechanism comprises a rotary plate, a gas transmission hole, a supporting ring, anannular slot, two power components and at least two lugs, wherein the power component comprises a sealing barrel, a sealing casing pipe, a spring, a piston block, a first check valve, a second checkvalve, a movement rod, a third pipeline and a fourth pipeline; and the circulation mechanism comprises a groove, a second pipeline, a filtering net, a first pipeline and a nozzle. In the numerical control drilling machine with the cooling liquid recycling and scrap cleaning function, through the scrap removal mechanism, scraps in a workpiece drilling hole can be removed, a possibility that the drill and a workpiece are stuck is lowered, a fault rate of the numerical control drilling machine is lowered, the cooling liquid can be recycled through the circulation mechanism, the loss of the cooling liquid is reduced, and the production cost of the numerical control drilling machine is lowered.
