Patent ID: 7021990

Claim:
A method for a circular grinding of a workpiece which has a workpiece axis and, while the method is being carried out, rotates about the workpiece axis, whilst at the same time a grinding wheel rotating about a grinding-wheel axis and the workpiece are advanced towards one another, in order to grind a first workpiece face which is designed to be rotationally symmetrical with respect to the workpiece axis the workpiece further having a second workpiece face which is designed to be rotationally symmetrical with respect to the workpiece axis and which is defined by a rectilinear generatrix, and the two workpiece faces being arranged adjacently to one another in such a way that a circular transition edge is formed between them, wherein, during grinding, an auxiliary abrasive tool, which rotates about an auxiliary-tool axis and has a plane abrasive surface arranged at right angles to the auxiliary-tool axis, is pressed against the workpiece in such a way that the abrasive surface is arranged in a tangential plane to the second workpiece face and touches the second workpiece face along a contact line the abrasive surface projecting in the direction of the contact line away from the second workpiece face beyond the transition edge.
