After seaming, grinding glass edges is another important work step in glass edge processing. The process is primarily used to remove overbreaks and underbreaks at the edges and to process the glass sheets to size. To this end, the edge processing removes an appropriate grind addition and the glass is thereby ground to the final size (custom ground edge "KMG"). This process also increases the edge strength, which significantly reduces spontaneous breakages. Glass lites sheets with ground edges exhibit a significantly higher strength against mechanical forces such as wind loads or thermal stresses. After grinding, the edge surfaces are matt ground and can sometimes also be used as visible edges. If the complete edge surface is ground, this is referred to as a finely adjusted edge ("KGN").
