Adjusting device for a gear cutting machine with a reduced tendency to vibrate

An adjusting device for a gear cutting machine, comprising:

• a base body;
• a movable body which is movable along a direction of movement relative to the base body;
• a drive for moving the movable body relative to the base body;
• an auxiliary body, which is releasably fixable to the base body and movable together with the movable body relative to the base body in a released state;
• a clamping device for releasably fixing the auxiliary body to the base body such that the auxiliary body and the base body form a rigid unit when the auxiliary body is fixed to the base body;
• and
• at least one vibration damper which is arranged between the auxiliary body and the movable body in such a manner that vibrations between the movable body and the rigid unit formed by the auxiliary body and the base body are damped by the at least one vibration damper when the auxiliary body is fixed to the base body,
• wherein the at least one vibration damper is further configured to follow a movement of the movable body in relation to the base body without a damping force of the at least one vibration damper counteracting said movement when the auxiliary body is in the released state,
• wherein the at least one vibration damper has damping characteristics that are modifiable, and
• wherein the adjusting device further comprises a device for performing a frequency response analysis, which is operatively connected to the at least one vibration damper in order to automatically modify the damping characteristics of the at least one vibration damper on the basis of a result of the frequency response analysis.
