Zusammenfassung:	The invention relates to a technical solution for determining centers and the spatial course of the centers of a hollow shaft rotatably clamped as a workpiece in a machine tool, which is machined on its outer surface at least in sections. It is the aim of the invention to provide a technical solution in this respect using methods other than ultrasound. This aim is solved by using a sensor operating according to the eddy current principle, whereby process-engineering and device-engineering features are described in more detail. L'invention concerne une solution technique pour déterminer des centres et le profil spatial des centres d'un arbre creux monté rotatif en tant que pièce dans une machine-outil, ledit arbre creux étant usiné au moins par endroits par enlèvement de copeaux au niveau de sa surface extérieure. L'invention a pour but de fournir une solution technique correspondante en utilisant des procédés autres que les ultrasons. A cet effet, on utilise un capteur fonctionnant selon le principe des courants de Foucault, les caractéristiques techniques du procédé et du dispositif étant décrites dans le descriptif.
