Glass Processing
In this video Martina Eliášová explains the various cold-working techniques used to cut and shape standard float glass panes after production. The video outlines that mechanical processing is a fundamental step all flat glass undergoes and includes key operations like cutting, grinding, and drilling. Several cutting methods are described: the traditional surface-cut and break method, diamond disc cutting for thicker glass, laser cutting, and water jet cutting, which has the advantage of avoiding thermal stress. The video also details edge grinding, a process crucial for safety, aesthetics, and increasing the glass's strength by removing micro-cracks from cutting. Furthermore, it covers drilling, typically performed with diamond-coated tubular drills, and notes the specific standards that govern hole placement and dimensions. A key point emphasized is that all mechanical processing must be completed before the glass undergoes any thermal tempering process. The video was produced by the Open GLASSroom project.
