    摘要： A machine tool includes a machine control unit to output control signals to drives for machine elements. A tool which machines a workpiece is thereby moved relative to the workpiece in a position-controlled manner. Arranged in a first region of one machine element is an active vibration damper to damp vibration in a second region of the machine elements as the workpiece is machined by the tool. In order to detect the vibration, a first sensor is arranged in the first region of the machine element and a second sensor is arranged on another machine element or in a different region of the one machine element. Actual values detected by the first and second sensors and corresponding target values are supplied to a dual controller which determines on the basis of these values, a resulting manipulated variable for the active vibration damper and actuates the active vibration damper accordingly.

    摘要： A machine tool includes a machine element and a vibration damper arranged on the machine element to damp a vibration mode that occurs during operation of the machine tool and is manifested at a tool center point of the machine tool and at a point of the machine element. The vibration damper is arranged on the point of the machine element, with the vibration mode having a vibration antinode at the point.

    摘要： The rotary workhead device, which is loaded on the table of a machine tool and onto which a workpiece to be machined is rotatably mounted, is equipped with: a base plate that is attached to the table of the machine tool; two rotary workheads that are provided on the base plate and disposed so that the axes of rotation coincide and the workpiece-fixing parts face each other; a guide means that is provided so as to be capable of moving at least one of the rotary workheads back and forth in the direction of the rotation axes; and an impelling means for impelling the one rotary workhead in a direction that separates or brings together the two rotary workheads. The rotary workhead device applies a tensile force or a compressive force on a workpiece, the respective ends of which are fixed between the two rotary workheads.
