Title
(EN) CHAMFERING APPARATUS AND METHOD OF MANUFACTURING GLASS SUBSTRATE FOR INFORMATION RECORDING MEDIUM
(FR) APPAREIL À CHANFREINER ET PROCÉDÉ DE FABRICATION D'UN SUBSTRAT EN VERRE POUR SUPPORT D'ENREGISTREMENT D'INFORMATIONS
Abstract
(EN)
The invention disclosed an apparatus for chamfering glass substrates use for the manufacturing of information recording medium. The apparatus comprising a first and a second claim jigs adapted to clamp the glass substrate during chamfering. A method for chamfering glass substrate is also disclosed. The method comprising a step of cleaning the clamp jigs faces at the end of each chamfering cycle so as to remove contaminants, including glass chips from the faces of the clamp jigs prior to introduction of the next glass disk onto the chamfering apparatus.
(FR)
L'invention concerne un appareil à chanfreiner des substrats en verre qui est utilisé pour la fabrication d'un support d'enregistrement d'informations. L'appareil comporte un premier et un second dispositif de serrage conçus pour serrer le substrat en verre pendant le chanfreinage. L'invention concerne également un procédé de chanfreinage d'un substrat en verre. Le procédé comporte une étape consistant à nettoyer les faces du dispositif de serrage à la fin de chaque cycle de chanfreinage de façon à éliminer les contaminants, comprenant des éclats de verre, des faces des dispositifs de serrage avant l'introduction du disque en verre suivant sur l'appareil de chanfreinage.
