Description

Verfahren zum Veredeln von Flachglas Das Veredeln von Flachglas erfolgt durch Schleifen und Polieren. Zum Polieren werden Polierblöcke verwendet, die an ihrer Arbeitsfläche mit Filz oder einem anderen zum Polieren geeigneten Werkstoff versehen sind.Process for finishing flat glass The finishing of flat glass takes place by grinding and polishing. Polishing blocks are used for polishing your work surface with felt or another material suitable for polishing are provided.

Das zur Verarbeitung verwendete unpolierte Flachglas hat vom Schneiden auf Maß allseitig scharfe Kanten. Zum Auspolieren der gesamten Fläche, also auch der Randflächen, ist es notwendig, mit dem Polierblock über die Kanten des Glases hinauszufahren. Das hat zur Folge, daß Teile der Blockfläche, die über die scharfen Kanten und Ecken hinausgehen müssen, abgeschert werden. Dadurch wird die Blockfläche, die eben sein soll, allmählich ballig, so daß die wirksame Arbeitsfläche erheblich verkleinert wird. Das trifft für alle Arten von Polierblöcken zu, ganz gleichgültig, wie sie bewegt werden.The unpolished flat glass used for processing has been cut Sharp edges on all sides to measure. For polishing out the entire surface, so too the edge surfaces, it is necessary to use the polishing block over the edges of the glass drive out. This has the consequence that parts of the block surface, which over the sharp Edges and corners have to be sheared off. This will make the block area, which should be flat, gradually spherical, so that the effective work surface is considerable is reduced. This applies to all types of polishing blocks, regardless of how they are moved.

Die Abrundung der Arbeitsfläche der Polierblöcke wird mit der Zeit immer stärker und die dadurch bedingte Verkleinerung der wirksamen Arbeitsfläche hat zur Folge, daß die Bearbeitungszeit wegen des nun ständig zu verkleinernden Vorschubes immer länger und der spezifische Flächendruck immer größer wird, was sich sehr nachteilig für die Qualität der Politur auswirkt. Die Politur wird ungleichmäßig, und es ergeben sich Wellen auf der Oberfläche. Bei der Verschiebung der Polierblöcke über die Kanten hinaus splittern oft auch Teile von den scharfen Kanten aus, die am Polierblock haftenbleiben und Risse auf der zu polierenden Oberfläche ergeben. Der Polierbelag der Blöcke hat wegen des hohen, durch die scharfen Kanten verursachten Verschleißes nur eine verhältnismäßig kurze Lebensdauer. Der Rand der Glasplatte muß außerdem in einer nicht unbedeutenden Breite als Abfall nach dem Polieren weggeschnitten werden.The rounding of the working surface of the polishing blocks will become with time ever stronger and the resulting reduction in the effective work surface has the consequence that the processing time has to be continuously reduced because of the Feed is getting longer and the specific surface pressure is getting bigger, what is very detrimental to the quality of the polish. The polish becomes uneven, and there are waves on the surface. When moving the Polishing blocks Beyond the edges, parts of the sharp edges often also splinter, the stick to the polishing block and result in cracks on the surface to be polished. The polished surface of the blocks has because of the high, caused by the sharp edges Wear only a relatively short service life. The edge of the glass plate must also be cut away in a not insignificant width as waste after polishing will.

Das Abfassen bzw. Abrunden scharfer Ecken und Kanten nach dem Zuschnitt der fertig polierten Platten, insbesondere auch Glasplatten, ist als bekannt vorauszusetzen.The drafting or rounding of sharp corners and edges after cutting of the completely polished plates, in particular also glass plates, is assumed to be known.

Der Zweck der Erfindung besteht nun darin, die Arbeitsfläche des Blockes plan zu halten und die mit ihrem Balligwerden verbundenen Nachteile zu vermeiden. Dies wird gemäß der Erfindung dadurch erreicht, daß die Kanten und Ecken der Flachglaszuschnitte vor dem Polieren gebrochen oder abgerundet werden. Dadurch wird der Polierbelag der Blöcke nicht mehr abgeschert, und die Arbeitsfläche des Blockes bleibt in ihrer ganzen Ausdehnung plan und wirksam. Damit werden die oben angeführten Nachteile für Polierwerkzeuge, Werkstück und Arbeitszeit vermieden. Die Glasplatte kann entweder genau oder fast genau tauf das vorgeschriebene Maß der fertigen Platte zugeschnitten werden, so daß sich kein oder wenig Abfall ergibt. ' Das Brechen oder Abrunden der Kanten kann entweder unmittelbar vor dem Polieren oder auch schon vor dem Schleifen vorgenommen werden.The purpose of the invention is now to create the working surface of the block keeping it flat and avoiding the disadvantages associated with its bulging. This is achieved according to the invention in that the edges and corners of the flat glass blanks be broken or rounded before polishing. This will make the polishing pad the blocks are no longer sheared off, and the working surface of the block remains in theirs entire expansion plan and effective. This eliminates the disadvantages listed above for polishing tools, workpiece and working time avoided. The glass plate can either cut exactly or almost exactly to the prescribed size of the finished panel so that there is little or no waste. 'Breaking or rounding off the Edges can either be done immediately before polishing or even before sanding be made.
