ABSTRACT:
A method for precision-grinding a bezel at the inlet of a bore of a workpiece, comprising the following steps:
a. generating a bezel at the inlet of the bore of the workpiece by grinding the workpiece at the inlet of the bore with a first grinding tool into a first shape defining an angle correspondingly slightly greater than a desired nominal angle;
b. honing the bore to generate a honed bore; and
c. again grinding the bezel to its nominal shape by means of a second grinding tool, while simultaneously guiding the second grinding tool in the honed bore by means of a pilot.
