Device machining materials by milling or drilling, and method therefor

A device for machining materials by milling and/or drilling, in particular for removing rock, concrete, minerals or coal, comprising:

• a tool drum mounted on a drum carrier and rotatable about a drum axis and in which a plurality of rotatable drivable tool shafts are mounted, which support machining tools at their ends projecting from the tool drum, at least two of the tool shafts being drivable by a common gear drive, which has output drive gears rotationally fixedly arranged on the tool shafts and a common drive element which interacts with the output drive gears;
• wherein the drive element and the tool drum are rotatable relative to each other, and having a movement device for moving the drum carrier relative to the material to be machined;
• a control device with which a speed of the relative movement between a tool carrier and material and the rotational speed of the tool drum is variable;
• at least one measuring sensor for measuring the translational vibration of the device and/or at least one measuring sensor for determining the rotational vibrations of the tool drum;
• wherein the control device comprises:
• at least one vibration analysis module, by which, in a vibration analysis, a vibration spectrum is determinable, and
• at least one controller module by which the rotational speed and/or the relative speed are controllable or are controlled as a function of the vibrations determined by the analysis module.
