Abstract

During grinding of mutually parallel edges of glass plates every edge of the glass plate is ground using a grinding tool or two grinding tools disposed one behind the other and cooling agent is directed from a side of the glass plate toward the grinding tool and supplied using a supply line divided via a redirection and separating segment into a plurality of fine streams of cooling agent, and a position of the grinding tool can be adjusted such that at least the position of the grinding tools relative to the assigned edge of the glass plate, which is passing through, is calibrated and the corners of the glass plate are ground to form a chamfer.
