Top surface quality thanks to vertical glass edge polishing

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.

Advantages of vertical systems for glass edge grinding

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").

How you enjoy major advantages with the professional seaming of glass edges

In glass edge processing, cutting the glass sheet is directly followed by the seaming process. Fully unprocessed glass edges exhibit overbreaks and underbreaks, conchoidal fractures, as well as micro-cracks along the broken edge. These types of damage are caused by the cutting wheels used in the cutting process. It is possible to reduce these cutting wheel-induced defects by using the cutting wheel at the appropriate angle for the respective glass, and by using a maintained cutting wheel axis and cutting wheel holder (service life in accordance with the manufacturer's specifications). This is important because any damage to the glass edge reduces the edge strength and in doing so also significantly increases the risk of spontaneous breakage.

Save time, money and stress with the right vertical glass edge processing

In glass edge processing, the requirements for the finished components can vary greatly depending on the location and purpose. The quality and the processing of the glass edge is extremely important, because it has a decisive influence on the strength - and therefore also on the service life - of the glass.

LiSEC SplitFin – The two towers!

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.

HOW BEST TO PREVENT MACHINE DOWNTIME

Performance data, investment costs, contribution margin, consumption of resources – the acquisition of a new glass processing system requires careful consideration. In addition to the production requirements for the scope of functions and the commercial calculation, there is another point to be clarified before the final decision is made: What happens if the line stops at an unplanned point?

CONCRETE ADVANTAGES OF MODULAR, SELF-CONFIGURABLE GLASS PROCESSING LINES

Higher integration density now plays a central role in the further development of systems. Extensions, add-ons and improvements are not only a question of the hardware, but also of the production processes, and with this also of the control and management systems. Modular solutions are advantageous both in terms of time and cost.

STANDARD FAST CYCLE TIMES IN GLASS PROCESSING THANKS TO INTEGRATED PRODUCTION LINES

Three different production concepts are currently used in flat glass production. But where high quantities and fast throughput are required, two of these concepts drop out of the race – they cannot keep up with the pace of the integrated line.
