Disclosed is a multiple spindle drilling machine that is improved to be able to drilling several bolt holes on a flange at once. The multiple spindle drilling machine comprises: a driving motor; a driving box reducing a driving force of the driving motor and delivering to a main spindle; a link box including the main spindle and multiple spindles engaged with the main spindle by a gear, the multiple spindle having a length adjusting groove at an end thereof and being driven as interlocked with the main spindle; multiple shanks combined to an adjusted position of the length adjusting grooves of the spindles in the link box to be able to adjust the lengths of the spindles; multiple drills respectively coupled to the shanks to drill bolt holes on a flange; a chuck for seating the flange on a table on which the multiple drills are arranged; a hydraulic cylinder lowering the chuck to load the flange and lifting the chuck to drilling the bolt holes on the flange; and a clamping part having clampers being rotated by interlocking with lifting or lowering of the chuck to fix the flange by being interlocked with the lifting or lowering of the chuck. |
