Hobbing machine, comprising a hobbing slide and a chamfering slide on a common rail system

A hobbing machine, comprising:

• a machine bed having arranged on it a workpiece spindle, by means of which a workpiece can be rotated about a workpiece axis;
• a rail system arranged on the machine bed, the rail system comprising at least one rail arranged on the machine bed, the rail system running in a first horizontal direction parallel to the workpiece axis;
• a hobbing head;
• at least one chamfering device;
• a first slide with a first slide guide system;
• wherein the hobbing head is arranged on the first slide;
• wherein the first slide, by means of its first slide guide system, is configured to slide on the at least one rail of the rail system in the first horizontal direction parallel to the workpiece axis;
• and
• a second slide with a second slide guide system;
• wherein the at least one chamfering device is arranged on the second slide;
• wherein the second slide, by means of its second slide guide system, is configured to slide on the at least one rail of the rail system in the first horizontal direction parallel to the workpiece axis;
• wherein the at least one rail of the rail system comprises at least one common rail that is used to guide both the first slide guide system and the second slide guide system, wherein each common rail is used in common to guide both the first slide guide system and the second slide guide system;
• wherein the hobbing head is configured to slide on and relative to the first slide in a second horizontal direction that is perpendicular to the workpiece axis;
• wherein the at least one chamfering device is configured to slide on and relative to the second slide in a third horizontal direction that is perpendicular to the workpiece axis;
• and
• wherein a first movement range of the first slide along the at least one common rail of the rail system and a second movement range of the second slide along the at least one common rail of the rail system overlap defining an identical portion of the rail system, wherein the first slide and the second slide can be displaced along the identical portion of the rail system such that the workpiece is configured to be machined by either the hobbing head or the at least one chamfering device;
• wherein the first slide is designed in the form of a driven slide, wherein a motor drive is provided for the driven slide and is configured to slide the driven slide on the at least one common rail in the first horizontal direction, wherein the second slide is designed in the form of a non-driven slide, and wherein a coupling device is provided mechanically connecting the driven slide and the non-driven slide so as to cause the non-driven slide to slide on the at least one common rail when the driven slide is driven to slide on the at least one common rail.
