Abstract
The invention relates to a method and a machine tool for hard finishing toothed gearing, particularly internally toothed portions (), 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 () of the machine tool gearing with tooth thickness increasing in the tooth trace direction from the end face () facing the machined toothed gearing.
