  • Patent number: 9981321
    Abstract: A tool (20) has a machine-side machine connection (21) for connecting the tool to a machine tool (1) for driving the tool in rotation (27) about a rotation axis (29) and for advancing (26) the tool relative to a workpiece, a workpiece-side tool head (22) having one or more cutting edges (25) for machining a workpiece, wherein the diameter (D) of the tool head is greater than 20 mm and wherein the cutting edges (25) of the tool (20) are arranged such that they travel over an area perpendicular to the rotation axis (29), a vibration unit (23) which is designed to set the tool head into rotary vibration (28) about the rotation axis (29), and a power receiving means (24) for wirelessly receiving supplied energy and for supplying electrical energy to the vibration unit (23).

  • Patent number: 9908209
    Abstract: In a method for machining a workpiece, a cutting tool is guided relative to the workpiece, with a vibration being superposed, the amplitude of which is at least 5 ?m. A supply circuit for a piezo actuator of a vibrating tool generates a voltage at the voltage output, which has a direct component and an alternating component. A supply system for a piezo actuator of a vibrating tool has the above-mentioned supply circuit which is connected to a secondary coil that is coupled to a primary coil.

  • Patent number: 9707655
    Abstract: In a method for machining a workpiece using a tool, the tool engages with the workpiece and between the two a cutting motion is induced. Furthermore, a relative first vibration motion between workpiece and tool, which is superimposed on the cutting motion, is induced in such a way that one or more characteristic values of the first vibration motion and one or more characteristic values of the cutting motion are adjusted in relation to one another. The superimposed vibration motion can also be induced in such a way that distinctive surface zones of the workpiece are generated.

  • Publication number: 20150314410
    Abstract: A tool (10) for machining a workpiece in a machine tool comprises a coupling portion (41) that is in operation on the machine-side and that may be standardized for coupling the tool with a numerically controlled machine tool (30), a tool portion (43) that is in operation on the workpiece-side for machining the workpiece, and a mid-portion (42) between the coupling portion (41) and the tool portion (43). The tool portion (43) comprises on the workpiece-side one or more suction air openings (15) in communication with suction air channel (16) inside the tool that leads to the mid-portion (42) of the tool. In the middle portion a connector (11) for a suction air connector (38, 39) is provided that is displaced. sideways relative to the tool axis.
