Numerical control machine tool

The invention discloses a numerical control machine tool, which comprises a processing chamber and a control chamber, wherein a cabin door is arranged on the outer surface of the processing chamber; an observation window is arranged on the outer surface of the cabin door; the numerical control machine tool is provided with a solid-liquid separator; metal chips generated through cutting and coolingliquid waste liquid enter the solid-liquid separator through a material guide plate; then, in the movement process, cooling liquid flows into a waste liquid box through a filtering screen; the cooling liquid is separated from the metal chips; a second motor drives a chain to rotate through a rotating shaft, and drives a scraping plate arranged on the surface of the chain to rotate; the scraping plate scrapes the metal chips and pushes the metal chips into a chip box; the blockage caused by chip accumulation is avoided; meanwhile, a filtering box is also installed; the air containing cooling liquid in the processing c
