Daimler 1 - Entzundern und Entgraten von hohlen Getiebehauptwellen G140-8

With conventional noncircular grinding the uneven shape of workpieces is created by pendular movement of a round grinding disk. In contrast with rpm-synchronous noncircular grinding the workpiece is machined with an unround grinding disk. In process the workpiece and the tool are turning with a certain rpm-ratio. With this special method it is possible to machine several types of unround shapes (e.g. all cams of a camshaft) with just one step of positioning.
