Abstract: The invention relates to a method and a machine tool for hard finishing toothed gearing, particularly internally toothed portions (3), in which method a toothed hard finishing tool (W) which rotates about its axis of rotation is brought into rolling machining engagement with the machined toothed gearing in one pass or in a plurality of passes of differing radial infeed depth under an advance motion with a direction component parallel to the axis of rotation (C) of the machined toothed gearing and under a non-null axis crossing angle, and material is removed from the machined toothed gearing with a tooth flank region (4a) of the machine tool gearing with tooth thickness increasing in the tooth trace direction from the end face (5) facing the machined toothed gearing.

Abstract: The invention relates to a method for creating or machining gears on workpieces (W1, W2), in which a rolling first machining engagement between a machining tool (WF; WS) that is driven about its rotation axis (B) and a first workpiece that is rotatable about the rotation axis (C1) of a first workpiece-side spindle (11) is realized at a first location on a gear-cutting machine (100; 200) by means of a tool-side spindle drive motor (22), and in which a second machining engagement is realized at a second workpiece, different from the first workpiece, that is rotatable about the rotation axis of a second workpiece-side spindle (12) that is different from the first workpiece-side spindle, wherein the machining tool can execute, relative to the first workpiece-side spindle, a movement, serving as an axial infeed movement in the first machining engagement, along a tool-side machine axis (Z) that has a direction component in the direction of the first workpiece-side spindle axis and in particular extends parallel the

Abstract: The invention concerns a method for the chip-removing generation or machining of gear teeth on a workpiece which is driven in rotary movement about its rotary axis at very high rates of rotation, with a toothed tool that is driven in rotary movement about its rotary axis, wherein the tool and the workpiece are brought into a rolling tooth engagement in the manner of a helical gear transmission with their axes of rotation crossing each other at an angle different from zero, and wherein a further operation is performed on the workpiece and/or on its gear teeth during the time of operating engagement between the teeth of the tool and of the workpiece.

Abstract: The invention concerns a method to generate and/or machine gear teeth on a workpiece, wherein the workpiece is subjected to a movement from a first location where the workpiece, while being held by a clamping device connected to a workpiece spindle, is brought into machining engagement with a first tool, to a second location where the work piece, while remaining in its clamped condition, is brought into machining engagement with a second tool, wherein prior to performing the movement, the connection between the clamping device and the workpiece spindle is released, and after the movement, the clamping device is connected to another workpiece spindle for the machining engagement with the second tool.

Abstract: The invention concerns a method for the chip-removing generation or machining of internal gear teeth on a workpiece which is rotatable about its rotary axis and radially delimits a free space that extends axially to one side beyond the internally toothed region and whose radial width narrows in the direction of its axial extension in at least one location. An externally toothed tool which is driven in rotary movement about its axis of rotation is brought from the opposite side into rolling engagement with the internally toothed region with the rotary axes crossed at an angle. Through the application of a mechanical force, the chips which are produced in the process and which are subject to a centrifugal force are caused to change their movement in the zone of narrowing width in a manner directed against the origin of the centrifugal force.
