Abstract

Es wird ein Verfahren zum Fertigstellen von Nockenscheiben mit einer in Achsrichtung liegenden zentralen Öffnung für eine Nockenwelle bereitgestellt, bei dem mehrere Nockenscheiben, insbesondere sämtliche für eine Welle bestimmte Nockenscheiben, mit deckungsgleichen Öffnungen zusammengespannt und mittels eines rotierenden Schleifwerkzeuges, dessen Drehachse im wesentlichen parallel zur Öffnungsachse der Nockenscheiben ausgerichtet ist, bearbeitet werden. Ein zusätzliches Formschleifwerkzeug kann einen Teil der Bearbeitung übernehmen. Die Nocken werden anschließend auf einem Rohr oder Stab in gewünschter Art festgelegt. Auf diese Weise werden in einem Vorgang sämtlichen Nocken einer Welle auf kurzer Spannlänge vor- bzw. fertiggeschliffen. There is a method of finishing cam disks with a Axial opening for a camshaft provided, in which several cam disks, in particular all cam discs intended for a shaft, with congruent openings clamped together and by means of a rotating grinding tool, the Axis of rotation essentially parallel to the opening axis of the cam discs is processed. An additional Form grinding tool can take over part of the machining. The Cams are then on a tube or rod in the desired way fixed. In this way, all cams are in one operation pre-ground or finished a shaft on a short span.
