Abstract
Apparatus for internally grinding rotationally-symmetrical workpieces, the grinding disc of which only abuts against the end face of the workpiece and has a generatrix which extends in a substantially flat manner and, by subtending a small clearance anle, is guided towards the area of the workpiece to be machined, a further clearance angle being formed by an offset disposition of the axes of the grinding disc and of the workpiece relative to one another, the point of contact between the grinding disc and the completely ground workpiece face being offset by a dimension D relative to the central axis of the workpiece.
