The invention relates to a method for reducing vibrations of a machine element () and/or a workpiece () in a machine tool, a production machine and/or in a machine which is embodied as a robot. A clamping force (F), which is used to lock the workpiece () and which makes the workpiece holder () act upon the workpiece (), is modified when vibrations occur. The invention also relates to a corresponding machine. Due to said invention, vibrations of a machine element () and/or a workpiece (), which occur during a machining process, are reduced.

A tool-changing device includes a tool gripper and a stroke and pivoting actuator for operating the tool gripper. The stroke and pivoting actuator can be driven by a first direct drive for producing a linear movement and by a second direct drive for producing a rotational movement, wherein the first and the second direct drives have a common rotor which serves as the stroke and pivoting actuator.

The invention relates to a machine comprising a mechanical guide element () for guiding the displacement of a first () and a second device (). The machine comprises a first drive device () for displacing the first device () along the guide element (), and a second drive device () for displacing the second device () along the same guide element () as the first device (). The mechanical construction of a machine is simplified due to said invention.

A protective device includes a signal input intended for connection to a sensor, a signal output intended for connection to an evaluation unit, and an isolation element for galvanically separating the signal input from the signal output. The provision of the protective device prevents a transmission of overvoltages from the sensor to the evaluating unit.
