Abstract:
1. A tool for polishing and fine-grinding optically active surfaces in precision optics comprising: a main body which can be attached in a rotationally fixed manner to a tool spindle of a machining machine; a guide element which is arranged concentrically in the main body and is mounted such that it can be displaced axially therein, said guide element having a full displacement travel; a machining disk which is replaceably attached to the outer end of the guide element and on the outer surface of which at least one of polishing and grinding means is provided; wherein the main body is rigidly connected in a rotationally fixed manner, over the full displacement travel, to the guide element mounted such that it can be displaced axially therein; wherein the machining disk is rigidly fixed in a non-tiltable manner on the guide element; and wherein the tool has a tool rotation axis and a stop pin is inserted in the guide element transversely to the tool rotation axis and, in order to connect the main body to the guide element in a rotationally fixed manner, engages in an axial groove which is provided in the main body and has two ends, and the axial groove having an axial length which limits the maximum displacement travel of the guide element in the main body, and wherein, by means of a spring force acting axially on the guide element, the guide element is displaced in a basic position of the tool until the stop pin comes into abutment against one of the ends of the axial groove.
