Method for profiling a turning flat key and turning flat key produced by the method based on a turning flat-plate profile

摘要

A method for profiling the broad sides (3, 3 ') of a turning flat key, wherein a key blank (1) is clamped in a clamping device such that its first broad side (3) is exposed, with a rotating about a cutter shaft (19) on its peripheral surface milling teeth (16) having cutter (17) by feeding in key longitudinal direction to the longitudinal section profile of the cutting teeth (16) complementary grooves (4, 5, 6, 12) and ribs (8, 9, 11) are milled and then the key blank (1 ) is clamped in a position rotated by 180 ° about the key longitudinal axis (10) in such a manner that its second broad side (3 ') is exposed, and with the same milling cutter (17) by grooves in the key longitudinal direction to the longitudinal section profile of the cutting teeth (16) 4, 5, 6, 12) and ribs (8, 9, 11) are milled into the broad side (3 '), characterized in that the cutter shaft axis to the longitudinal center plane (2) of the key (1) u m an inclination angle (φ) is inclined, wherein at least one cutting tooth rib of the cutting teeth (16) has an undercut guide wall (4 ') ...
