ABSTRACT:
In a method for the inductive surface hardening of workpieces with any desired external geometries, especially camshafts for internal combustion engines, an inductor (15) is provided which at least partially surrounds the workpiece (2 or 4). The workpiece (2 or 4) executes a uniform rolling motion, and, given a constant coupling distance (X), the internal contour (18) of the inductor (15) represents a line parallel to the rolling contour (16) of the workpiece (2 or 4).
