DEVICE FOR EDGING AN OPTICAL LENS AND PROCESS FOR PRODUCING OPTICAL LENSES

摘要

a device (10) for processing an edge (e) of a disc for a lens (l) and, in particular, brillenlinse, includes a host body (12) to hold at a blockstu00fcck (s) blocked linsenrohlings in a workspace (14) of the randbearbeitungsvorrichtung, a bearbeitungse thanks to (16), by means of a tool (w) for the processing of the edge antreibbar isand a bewegungseinrichtung (18) for generating a relative movement between linsenrohling and tool during the machining of the edge in the space.to simplify and improve the handling process in connection with the broadcast of the treated, especially on the edge of the randbearbeitungsvorrichtung processed lens has a abblockeinrichtung (20), through the lens of blockstu00fcck abblockbar in the work area.also, a process for lens or eye glasses is proposed, which abblock - hauptschritt a grooving signature includes, in the basis of the edge of the blockstu00fccks adjacent to or near a first surface of the lens of a puncture is generated at the other abblocke as solltrennstelle between brillenlinse and blockstu00fcck serves.
