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. The ring element is supported by a support ring, on which at least one support element associated with the support ring opening of the support ring is provided. The ring element is supported on said support element. The teeth of the set of internal teeth formed on the ring element protrude beyond the edge of the support element facing the support ring opening at least over part of the length of the cutting edges of said teeth in the direction of the central longitudinal axis of the tool.
