Abstract
A polishing device for polishing optical lenses having a tiltable base part for directly or indirectly receiving a polishing plate, which base part is connected to a polishing spindle having an axis of rotation D in order to be rotationally driven, wherein a rotary joint for supplying a polishing agent is provided, which rotary joint is at least partly arranged opposite said polishing spindle, relative to the base part, and a coupling element is provided by means of which the rotary joint can be detachably push-fitted or clipped onto a polishing spindle. A method for polishing selected zones of aspherical lenses which are not rotationally symmetric using a polishing plate which is guided by a polishing spindle so as to be tiltable, wherein during polishing, a polishing agent is introduced between said polishing plate and the lens via a rotary joint arranged between said polishing spindle and said polishing plate.
