Method and apparatus for circular grinding










Image Number 3 for United States Patent #7021990.

A method and apparatus for a circular grinding of a workpiece having first and second workpiece faces which are rotationally symmetrical with respect to the workpiece axis and which form a circular transition edge between them are provided. The workpiece rotating about its axis and a grinding wheel rotating about a grinding-wheel axis are advanced towards one another. 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 plane abrasive surface projects in the direction of the contact line away from the second workpiece face beyond the transition edge.
