    Abstract: A tool for producing an internal thread in a workpiece pilot hole having a thread major diameter and a thread minor diameter, which tool has a thread-forming section, by which an internal thread profile can be produced in a pilot hole wall. The internal thread profile having the thread major diameter and a thread inner diameter. The tool has a drilling section, by which the thread inner diameter of the internal thread profile can be expanded to the thread minor diameter by machining. At least one, in particular exactly one chip groove is associated with the drilling section of the tool, by which chip groove the chips produced as the thread inner diameter is expanded to the thread minor diameter can be transported away.

    Abstract: A method for producing a threaded hole in a workpiece with a thread tapping tool bit, which, at its drill bit tip, has a main cutting edge and a thread profile that trails in a thread tapping direction with at least one thread cutting tooth, wherein, in a thread tapping stroke, the main cutting edge produces a core hole, and, at the same time, the thread profile forms an internal thread at the inner wall of the core hole until a target thread depth is reached, and this is conducted with a thread tapping advance in the thread tapping direction and at a thread tapping rotational speed of the thread tapping tool bit synchronized therewith. After the thread tapping stroke, an oppositely directed reversing stroke is produced, in which the thread tapping tool bit is withdrawn out from the threaded hole in a reversing direction and, in fact, this is conducted with an opposite reversing feed.

    Abstract: A method and a device for facing surfaces of workpieces, in particular made of light metal alloys, in which a cutting tool is moved in a feed direction relative to the surface and removes material at a defined thickness by cutting, wherein the cutting tool is moved in a defined feed direction with one or more cutter bars oriented substantially parallel to the surface. The cutter bars are always set at an angle of 0° with respect to the feed direction. In this way, surfaces with high surface quality can be produced, in particular for workpieces made of light metal, with cost-effective machining parameters.

    Abstract: A method for producing a thread can include a) generating a number n≧1 of twisted grooves in a wall of the workpiece encircling a thread axis (M) or generating a wall of the workpiece which has a number n≧1 of twisted grooves and encircles a thread axis, b) respectively inserting a thread generating region of a tool into each of the twisted grooves in a twisted insertion movement, c) generating a thread in each wall sub-region, adjoining the groove(s), of the wall of the workpiece by rotating the tool about the thread axis (M) and with a simultaneous axial feed motion of the tool coaxially with respect to the thread axis with a particular axial feed speed and d) moving each thread generating region of the tool out of the associated groove in a twisted removal movement matched to the twisting of the associated twisted groove.

    Abstract: A milling tool for face milling a substantially flat workpiece surface includes at least one main cutting element rotatable in a rotation direction about a tool axis oriented at a right angle to the workpiece surface and movable transversely to the tool axis and along the workpiece surface. The main cutting element includes a face cutter having a radially outer cutting edge corner and adapted to remove material from the workpiece surface up to maximal a nominal size. At least one clearance groove cutting element is provided and leads the main cutting element in the rotation direction to produce in the workpiece surface a clearance groove, in which the radially outer cutting edge corner of the main cutting element is guided substantially without being subjected to cutting stress.

    Abstract: A drilling tool, in particular a reamer, for drilling out a workpiece core bore to a nominal diameter by means of a main blade formed on a drill body is disclosed. The main blade has a radially external cutting edge which extends along a drill-body longitudinal axis as far as a blade corner arranged at the drill tip, wherein during the drilling-out operation, the drilling tool is drivable into the workpiece core bore with a rotary movement and a feed movement. The drilling tool has at least one groove blade which is arranged so as to precede the blade corner of the main blade in the direction of rotation of the tool. During the drilling-out operation, the groove blade produces a groove in the inner wall of the core bore drilling, the blade corner of the main blade being guided in the groove with an at least reduced cutting load.
