The worms of the worm wheel drives being adapted alternately to be drivingly connected to a drive shaft. The worms of the worm wheel drives are drivingly connected to each other while the transmission ratio of this transmission connection of the two worms equals the reciprocal transmission ratio of the worm wheel drives with regard to each other. The worm wheels of both worm wheel drives which are rotated in the same direction and at equal speed which latter depends on the respective coupled worm wheel drive, are coupled to each other as well as to the workpiece table.
