The invention relates to the technical field of
numerical control drilling
machine tools, and discloses a
numerical control drilling
machine tool. When the
numerical control machine tool controls the connecting shaft to move downwards,
airflow sprayed out of the air guide hole preferentially sprays sweeps in a
drill hole upwards, the
cutting cutter head can continuously
cut up long sweeps generated in the
drill hole when the
drill bit drills, on one hand, the long sweeps can be conveniently sprayed out through the
airflow, on the other hand, winding of the sweeps is avoided, and the
cutting efficiency is improved. And finally, the numerical control
machine tool controls the connecting shaft to move upwards, at the moment, the
chip removal block pops up to further
discharge the waste chips remaining in the
drill hole, finally, the effects of
cutting the long waste chips to avoid winding and rapidly discharging the chopped waste chips are achieved, and the problem that when the
drill hole is too deep and the waste chips are too long, the waste chips cannot be
cut is solved. And long sweeps at the bottom of a drilled hole cannot be quickly discharged through short-distance up-down
reciprocating motion, and the risk that the sweeps are wound still exists.
