Abstract

Die Erfindung bezieht sich auf einen Polierkopf 1 für Brillenflächen 8.1 mit einem Grundkörper 2 zum Befestigen an einer Polierspindel 7, mit einem elastischen Trägerteil 3 für eine angebrachte bzw. anzubringende Polierfolie 4, wobei das Trägerteil 3 eine Aussparung 3.1 mit einer Wandfläche 3.2 und einer Tiefe t und die Polierfolie 4 mindestens ein Loch 4.1 aufweist, wobei das Loch 4.1 einen Zugang zu der Aussparung 3.1 bildet, wobei die Polierfolie 4 zusätzlich zu dem Loch 4.1 mindestens ein weiteres Loch 4.4 aufweist, welches im Bereich eines Randes 3.3 der Aussparung 3.1 angeordnet ist und zum Loch 4.1 einen radialen Abstand a aufweist, wobei das weitere Loch 4.4 einen Ausflusskanal für Poliermittel aus der Aussparung 3.1 heraus bildet oder die Wandfläche 3.2 zumindest über einen Teil der Tiefe t und/oder mit Bezug zu einem Umfang zumindest segmentweise gegenüber der Drehachse D in einem Winkel α angestellt ist, und/oder das Trägerteil 3 mindestens eine in der Stirnseite 3.3 vorgesehene Nut 3.5 mit einem Nutgrund 3.6 und einer Tiefe t1 aufweist, die an die Aussparung 3.1 anschließt, und/oder das Trägerteil 3 mindestens einen die Aussparung 3.1 und die Stirnseite 3.3 verbindenden Kanal 3.7 mit einer Öffnung 3.7a aufweist.The invention relates to a polishing head 1 for spectacle surfaces 8.1 with a base body 2 for attachment to a polishing spindle 7, with an elastic support member 3 for an attached or to be attached polishing foil 4, wherein the support member 3 has a recess 3.1 with a wall surface 3.2 and a depth t and the polishing film 4 has at least one hole 4.1, wherein the hole 4.1 forms an access to the recess 3.1, wherein the polishing film 4 in addition to the hole 4.1 at least one further hole 4.4, which is arranged in the region of an edge 3.3 of the recess 3.1 and to the hole 4.1 has a radial distance a, wherein the further hole 4.4 forms an outflow channel for polishing from the recess 3.1 out or the wall surface 3.2 at least over a part of the depth t and / or with respect to a circumference at least segmentally with respect to the rotation axis D. is set at an angle α, and / or the support member 3 at least one in the Stirnsei te 3.3 provided groove 3.5 having a groove base 3.6 and a depth t1, which connects to the recess 3.1, and / or the support part 3 at least one of the recess 3.1 and the end face 3.3 connecting channel 3.7 having an opening 3.7a.

Die Erfindung bezieht sich auch auf ein Verfahren, bei dem vor dem Zusammenführen von Polierkopf 1 und zu polierender Fläche 8.1 ein Vorrat an Poliermittel in die Aussparung 3.1 im Trägerteil 3 eingefüllt wird.

Figure imgaf001
The invention also relates to a method in which prior to merging the polishing head 1 and the surface to be polished, a supply of polishing agent is introduced into the recess 3.1 in the carrier part 3.
