Patent number: 9908209Abstract: 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.Type: GrantFiled: October 18, 2013Date of Patent: March 6, 2018Assignee: SAUER ULTRASONIC GMBHInventor: Jens Ketelaer

Patent number: 9707655Abstract: 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.Type: GrantFiled: June 14, 2012Date of Patent: July 18, 2017Assignee: Sauer Ultrasonic GMBHInventor: Axel Hessenkämper

Publication number: 20150314410Abstract: 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.Type: ApplicationFiled: December 5, 2013Publication date: November 5, 2015Applicant: Sauer Ultrasonic GmbHInventor: Florian Feucht
