Common Glass Edge Treatments
Glass edging can be done to improve a glass’s dimensional tolerance, functionality, cleanliness, appearance, and even resistance to chipping. Abrisa Technologies' edging treatments include cut/seam, machine ground (pencil and flat), and machine polished (pencil and flat).
Abrisa Technologies can fabricate many edge treatments for the various glass substrates we provide. The edge treatment selected can affect functionality and performance. Edging is done for safety, cosmetics, functionality, cleanliness, improved dimensional tolerance, and to prevent chipping. Edging is generally described as a grinding process used to remove the sharp or raw edge of cut glass.
The most common edge treatments done at Abrisa Technologies are:
Cut/Seam – this is often called a safety seam edge or swiped edge, the primary purpose is to remove the sharp edges; it is not a smooth cosmetically finished edge. A sanding belt is used to lightly sand off the sharp edge of the glass.
Machine Ground – Diamond embedded grinding wheel put a satin finish on the edge
- Pencil – edge has a radius similar to pencil of a “C-shape”.
- Flat – a flat edge with a small 45 degree chamfer on the very top and bottom.
Machine Polished – Taking a ground edge another step, polishing the edges to give the glass a nice sheen finish.
- Pencil – edge has a radius similar to pencil of a “C-shape”.
- Flat – a flat edge with a small 45 degree chamfer on the very top and bottom.
