Gantry machining center with good cooling effect

The gantry machining center with the good cooling effect comprises a spindle box, a cooling liquid box is fixedly installed on the front face of the spindle box, and a cooling mechanism is installed on the left side of the cooling liquid box. And the cooling mechanism comprises a supporting rod, the supporting rod is fixedly installed on the left side of the cooling liquid box, and a micro motor is installed in the supporting rod. According to the gantry machining center with the good cooling effect, when a workpiece is machined, a water pump is started, so that cooling liquid in a cooling liquid box is conveyed into a splitter plate from a liquid conveying pipe and is sprayed out from a plurality of spraying holes, meanwhile, a micro motor is started to drive a threaded rod to rotate, a threaded block moves upwards, and a connecting rod can pull a movable plate to rotate; and then the micro motor rotates reversely to enable the movable plate to rotate back to the original position, the drill bit is cooled wh
