Abstract
A hobbing machine for manufacturing spur and worm gears comprises a tool support provided with a support carriage movable in the direction of the axis of the blank to be machined and carrying a milling head provided with a separate feed drive which actuates via a branch gearing axial and tangential feed gear element and is connected via differential gears to a gear train for a hob. The branch gearing is arranged in the movable support carriage and includes a switch wheel which is engageable either with a drive wheel of the axial feed gear train or with the drive wheel of the tangential feed gear train and is controlled by a switching lever located on the support carriage.
