The present disclosure relates to a gear cutting machine, having a workpiece mount and a first tool mount for a respective workpiece and tool. The first tool mount can be set into rotation about a first axis of rotation of the gear cutting machine and the workpiece mount can be set into rotation about a second axis of rotation of the gear cutting machine. The first tool mount is arranged at a machining head which is movable parallel to the second axis of rotation of the workpiece mount at a machining head over at least one first linear movement axis of the gear cutting machine. In accordance with the present disclosure, the gear cutting machine furthermore has a second machining head having a second tool mount which is movable over a second linear movement axis parallel to the first linear movement axis independently of the first machining head.
A gear cutting machine, having a workpiece mount and a first tool mount which are movable relative to one another over movement axes of the gear cutting machine for gear cutting processing by a tool clamped in the first tool mount of a workpiece clamped in the workpiece mount, wherein the first tool mount is settable into rotation about a first axis of rotation of the gear cutting machine and the workpiece mount is settable into rotation about a second axis of rotation of the gear cutting machine and wherein the first tool mount is arranged at a first machining head which is movable parallel to the second axis of rotation via at least one first linear movement axis of the gear cutting machine and wherein the gear cutting machine has a control for the automatic control of the movement axes of the gear cutting machine during the gear cutting processing of the workpiece and/or during dressing of the tool, wherein the gear cutting machine furthermore has a second machining head with a second tool mount and a second axis of rotation which is moved independently of the first machining head via a second linear movement axis parallel to the first linear movement axis.
A method of operating a gear cutting machine, having a first and a second machining head which are movable independently of one another for gear cutting processing of a workpiece clamped in a workpiece mount, wherein both machining heads are used simultaneously at different Z positions in dependence on a vertical offset of a line of engagement in order to correct the vertical offset of the line of engagement between left and right flanks.
A method of operating a gear cutting machine having a first and a second machining head which can be moved independently of one another for gear cutting processing of a workpiece clamped in a workpiece mount and having a dressing unit, comprising using the dressing unit to dress a tool arranged at the first and/or second machining head, wherein the first and second machining heads are used alternately for the gear cutting processing of one or more workpieces.
