Title (EN) METHODS AND APPARATUS FOR FINISHING EDGES OF GLASS SHEETS
(FR) PROCÉDÉS ET APPAREIL DE FINITION DE BORDS DE FEUILLES DE VERRE
Abstract:
(EN) A method for finishing an edge of a glass sheet comprises grinding the edge of the glass sheet with a grinding wheel. The glass sheet includes a first major surface, a second major surface substantially parallel to the first major surface, and the edge connecting the first and second major surfaces. The grinding produces a central edge portion and two chamfered edge portions connecting the central edge portion with the first and second major surfaces, respectively. The method further comprises polishing the central edge portion with at least one cup wheel rotated about a first axis substantially parallel with the first and second major surfaces of the glass sheet to polish the central edge portion, wherein an abrasive layer of the cup wheel comprises at least one of ferric oxide (Fe2O3), silicon carbide (SiC), and ceric oxide (CeO2).
(FR) L'invention concerne un procédé de finition d'un bord d'une feuille de verre, comprenant le meulage à la meule du bord de la feuille de verre. La feuille de verre comprend une première surface principale, une seconde surface principale sensiblement parallèle à la première surface principale, et le bord reliant les première et seconde surfaces principales. Le meulage produit une partie de bord centrale et deux parties de bord chanfreinées reliant la partie de bord centrale respectivement à la première et à la seconde surface principale. Le procédé comprend en outre le polissage de la partie de bord centrale avec au moins une meule boisseau mise en rotation autour d'un premier axe sensiblement parallèle aux première et seconde surfaces principales de la feuille de verre, afin de polir la partie de bord centrale, une couche abrasive de la meule boisseau comprenant au moins un oxyde ferrique (Fe 2 O 3 ), du carbure de silicium (SiC) et de l'oxyde cérique (Ce O 2) .
