Abstract
The invention concerns a gear-cutting machine for the machining of gear teeth with a gear-cutting tool driven in rotary movement about its tool axis, further with an assembly that includes a tool holder for the gear-cutting tool and is rotatably mounted on a carrier, allowing the tool axis to be set in a desired orientation, with an actuator device through which the assembly can be set to a desired angular position, and with a locking device that allows the assembly to be secured against being dislodged from the set angular position. According to the invention, a protruding arm that is a functional element of the actuator device is coupled to the assembly through a non-rotatable connection.

Gear-cutting machine for the machining of gear teeth with a gear-cutting tool driven in rotary movement about its tool axis, comprising
- an assembly (60) that includes a tool holder for the gear-cutting tool and is rotatably mounted on a carrier (50, 40), allowing the tool axis (Y) to be set in a desired orientation,
- an actuator device through which the assembly can be set to a desired angular position, and
- a locking device that allows the assembly to be secured against being dislodged from a set angular position,
- characterized by a protruding arm (70) that is coupled to the assembly through a non-rotatable connection and is a functional element of the actuator device.
Method for the machining of gear teeth with a machining tool driven in rotary movement about its tool axis and at a prescribed orientation of the tool axis, wherein
- as a first step, the tool axis is set to, and locked at, the prescribed orientation, and next prior to and/or during the machining, a relative movement is executed between the tooth-cutting tool and the toothed workpiece,
- characterized in that the setting of the orientation of the tool axis and the execution of the relative movement are actuated by the same drive mechanism.
