Abstract: The invention relates to a hobbing machine for simultaneously hobbing n workpieces, comprising an n-fold milling head having n milling spindle axes that are parallel to one another, an n-fold tailstock and an n-fold workpiece spindle carrier having n workpiece spindle axes that are parallel to each other in a first horizontal main axis direction. The n-fold workpiece spindle carrier and the n-fold tailstock comprise n workpiece spindle carrier units or tailstock units which can be moved individually in a second horizontal main axis direction perpendicular to the first horizontal main axis direction along horizontal movement axes.
