The invention discloses a numerical control lathe capable of recycling cutting fluid. The numerical control lathe comprises a bottom box, a display screen, a processing chamber, a workbench, a first motor, a cutting fluid recycling device, a first camera, a second camera, a third camera and a light, wherein a waste box is arranged at the right end of the bottom box; a connection seat is welded tothe upper end of the bottom box; the cutting fluid is collected by a recycling tank through the filtration of a first filter screen; at the same time, iron filings are pushed into the waste box by a pushing mechanism so that the cutting fluid cannot be wasted and the iron filings cannot be scattered and can be convenient to remove subsequently; the collected cutting fluid is pumped into a liquid collecting tank by a first liquid suction pump through a second filter screen and is pumped by a second liquid suction pump to be conveyed to a hydrojet pipe to spray, so that after recycling, the effect of reusing is achieved; the first camera, the second camera and the third camera monitor processing conditions in a processing chamber in real time; and after being processed by a single chip microcomputer, the processing conditions are displayed on the display screen so that the worker can observe the processing conditions in real time.
