Abstract: The invention relates to a tool for dressing or cutting teeth of fine machining tools, which tool makes it possible to exactly reproduce, in a simple manner, the required tooth system geometry on the fine machining tool which is to be dressed or in which teeth are to be cut. The tool is annular and has a set of internal teeth, the teeth of which mesh, during the tooth-cutting or dressing operation, with the set of external teeth of the fine machining tool in which teeth are to be cut or which is to be dressed. At the same time, the tool has a central longitudinal axis, which extends through the centre point of the opening surrounded by the tool. According to the invention, the set of internal teeth is now formed on a ring element, which is at most 5 mm thick and is produced from a diamond material. The teeth of the set of internal teeth have cutting edges, by means of which said teeth remove material of the fine tool during the tooth-cutting or dressing machining process.

Abstract: The invention relates to a peeling wheel for manufacturing a toothing on a gear wheel by skiving. The peeling wheel includes a toothing, which is formed by a plurality of equally shaped cutting teeth arranged and distributed around the rotational axis of the peeling wheel at a first pitch and at least one deviating cutting tooth, whose shape is different from the shape of the equally shaped cutting teeth. The cutting teeth include cutting edges with which they come into chip removing engagement with the material of the gear wheel during the skiving processing. In order to be able to produce toothings with such a peeling wheel with increased freedom in the design, the invention proposes that the deviating cutting tooth is arranged outside of the first pitch (p). The invention also relates to a method for producing a toothing on a gear wheel by skiving using a peeling wheel.

Abstract: The invention discloses a method for producing modifications, such as twists, on the tooth flanks of an internally-toothed workpiece by an externally-toothed tool. In order to carry out such a method also with machine tools, which have a reduced number of adjustable axes, the invention provides that the tool is dressed by arranging an internally-toothed dressing tool on the workpiece spindle of the machine tool at the position intended for the workpiece to be respectively honed and by bringing the dressing tool into engagement with the tool to be dressed. The width of the teeth of the dressing tool is smaller than the width of the tool to be dressed such that the dressing tool must be moved by a length along the workpiece longitudinal axis which corresponds to a multiple of the width of the teeth of the dressing tool. Subsequently, the fine machining of the workpiece takes place with the tool dressed in this manner.
