Deviation-preventing numerical control machining drilling machine

The utility model discloses a numerical control machining drilling machine capable of preventing deviation, which belongs to the technical field of numerical control machining drilling machines, and adopts the technical scheme that the numerical control machining drilling machine comprises a drilling machine body, a grid plate is mounted between two U-shaped mounting blocks, the lower end surface of the drilling machine body is communicated with a bin hopper, and the upper end surfaces of four supporting columns are fixedly connected with a water tank; the lower end face of the water tank communicates with two conveying pipes, electromagnetic valves are installed on the outer side walls of the two conveying pipes correspondingly, high-pressure spray heads are installed on the lower end faces of the two connecting pipes correspondingly, and therefore the effect of preventing impurities and sweeps from splashing to injure workers during workpiece machining is achieved. And impurities and sweeps in the two clamp
