  • Edge grinding apparatus and method for grinding glass substrate
    Patent number: 9283652
    Abstract: An edge grinding apparatus and method for grinding a glass substrate, with which a glass substrate can be ground by a fixed amount and the occurrence of defects can be minimized. The edge grinding apparatus includes an edge grinding unit which grinds a cut edge of a glass substrate while following the cut edge; a measuring unit which obtains positional information of the cut edge; and a control unit which receives the positional information of the cut edge from the measuring unit and controls a position of the edge grinding unit based on the positional information of the cut edge.
