摘要： A multiple spindle drilling machine can simultaneously drill a plurality of bores for inserting the rivets or the bolts through the web and a pair of flanges of wide flange beams which are used in building and construction by a first, second and third drilling assembly. A supporting device mounted on the upper side of a machine table which stops the wide flange beam is fed by a feeding device thereon and supports it at a predetermined drilling position. The first drilling assembly is mounted so as to be movable toward the vertical direction from the upper position of the machine table and has multi-drills for drilling a plurality of bores through the web of the wide flange beam. The second and third drilling assemblies are mounted so as to be movable toward the horizontal direction from both of the side positions of the machine table and have multi-drills for drilling a plurality of bores through both flanges of the wide flange beam.
