Abstract
A system performing a conical transition from a shaft to the core diameter of a worm is disclosed. The disclosed system includes inserting a rough milling machine in an axial direction before a disk milling machine used for milling the worm. The rough milling machine is especially manufactured integrally with the disk milling machine. The teeth of the rough milling machine are shorter than the teeth on the disk milling machine, and the teeth of the rough milling machine preferably define a truncated-cone shaped covering.
