Numerical control lathe for synchronously cleaning away cutting scraps in time

The invention discloses a numerical control lathe for synchronously cleaning away cutting scraps in time. The lathe comprises a shell. The upper surface of the shell is fixedly connected with the lower surfaces of two side plates. The upper surfaces of the two side plates are fixedly connected with the lower surface of a top plate. The lower surface of the top plate is fixedly connected with a machine body through a bolt. A motor a is started by an external power supply, an output shaft of the motor a rotates and drives two smashing rollers to rotate oppositely through a coupler, a rotating shaft a, a gear a, a gear b and a rotating shaft b, when the scraps pass through a material guide plate and enter the shell, the scraps are smashed under the effect of the smashing rollers, the blockagecaused by scrap accumulation is prevented, an air compressor pumps in air to compress the air, the compressed air is then sprayed out of an air nozzle through a telescopic hose, and therefore the scraps are blown off the mat
