A laser coordinate drilling machine comprises a base, a stand, a headstock and two planar laser beam generators, etc. The laser beam generators are mounted on the stand or the headstock directly or through one or two fixers. The midline of one generator is located on the fore-and-aft central plane of the spindle and the midline of the other generator is located on the right-and-left central plane of the spindle. The two generators are mounted downwards or aslant with respect to the spindle. The generated planar laser beams are superposed with the fore-and-aft and right-and-left central planes. Said laser beam generator comprises a laser generator, which can generate straight beam, and a lens for broadening the beam that is mounted in front of the laser generator. Due to the lenses, the two laser beams can form integrated X-Y rectangular coordinates, which includes X-axis, Y-axis and their scales and characters on the table. The drilling machine can position rapidly and exactly the place of the drilling hole and can adjust the position of the work quantificationally on the basis of the rectangular coordinates. It is so convenient and rapid that it can be applied widely on the drilling machine, the drilling and milling machine and other machines for boring hole.
