Abstract
A multi-spindle drilling machine with a plurality of separate driven shafts for drilling or cutting threads, and which are operable through an intermediate transmission, for example, a twelve-speed mechanism, and through a distributor mechanism operated by the intermediate transmission and equipped with several floors, with the help of which the number of revolutions and the direction of rotation of the driven shafts can be regulated, characterized in that the intermediate transmission acts on the distributor mechanism through two transmission shafts, that the first is driven directly by the intermediate transmission, while the second is driven by the first through a commutator group, which serves to reverse the direction of rotation and which preferably reduces the number of revolutions of the second transmission shaft.
