Abstract:
1. A method for profiling at least one broad side of a flat key, comprising the steps of: clamping a key blank in a clamping device so that the broad side of the key blank is exposed; and milling guide grooves and variation grooves which are complementary to a longitudinal sectional profile of cutter teeth into the broad side by advancing in a longitudinal direction of the key, in one work operation in a single pass of the key blank, using a milling cutter that has cutter teeth on its peripheral surface and rotates about a cutter shaft, the milling producing an undercut guide wall using at least one rib by inclining a rotational axis of the cutter shaft at an angle of inclination relative to a longitudinal center plane of key ribs of the cutter teeth that is greater than 0° and less than 90°.
