Polishing glass edges is the most sensitive task in glass edge processing because it largely involves visible edges, which means that almost no tolerances or errors are admissible. The target: Very high surface quality (matt areas are not permitted here), as well as rapid throughput times and extensive flexibility. Prior to this work step, the edge must be ground to the requisite dimensions. Rough and fine grinding take place initially with peripheral wheels, followed by polishing with stone peripheral wheels. It is specifically due to this large number of process steps that glass edge polishing is so elaborate and complex. For this reason, glass edge polishing only takes place if the glass components are to be used for decorative purposes or in furniture pieces and furnishings such as glass tables, frameless glass sheets, mirrors, sliding glass walls, display cabinets or display windows.

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").

Since the beginning of the 1990s, LiSEC has been actively shaping the cutting possibilities of laminated glass. Several successful innovations have already been introduced to the market based on years of experience. At glasstec 2018 the latest generation of LiSEC laminated glass cutting machines was presented: the VSL-A.

LiSEC has stood for quality glass processing with peripheral wheels for over 20 years now. Previously, this was primarily realised with so-called vertical all-in-one or combination machines (BAZ, KBF, etc.). The advantages of these machines lie in particular in the processing of large and complex sheets, because additional glass manipulations are omitted and the products can be fully produced in a single work step.

Even the best machines are not immune to PC faults. You can significantly reduce the consequences of system downtime with backups. To find out how you can create backups for your LiSEC machines and what the advantages of these are for you, check out this blog post.
