External and internal applications including;
Cutting
Laminated glass has to be cut in laminated glass cutting table. Both sides of the laminated glass are cut at the same time. Then the glass is broken/snapped off from the top and the bottom automatically. Cutting laminated glass on float glass cutting table is inconvenient and takes longer time. Furthermore, turning difficulty can cause the glass to break from the uncut side. Our customers using this type of cutting tables should first cut X, then Y according to the sizes being required. Especially for laminated glasses with 3+3 and 4+4 mm thicknesses, which are cut at the same time at X and Y and separated, undesirable breakages can occur while turning the uncut side with a crane.
Scoring length (3210-6000), feeding type, transporting type, heating equipment (IR mid wave), cutting head precision, minimum cutting length, breaking equipment and tilting availability are key factors when choosing a laminated glass cutting table.
Referring to cutting laminated glass, even though there are various applications of machine manufacturers, volatile or washable cutting oil is recommended. Kerosene should not be used for cutting. The dust and particles on the feeding table should be cleaned with air before the cutting process. Therefore the need to clean photocells, LEDs and switches on the cutting system is reduced. PVB bulges at the edges of the laminated glass occur during the production and can not be avoided. These bulges can be skimmed with cutting wheel to ensure precision.
Depending on the glass thickness, different angles of cutting diamonds are used for cutting laminated glass as in float/annealed glass cutting. For 3+3 135o, for 4+4 145o for 6+6 145o or 156o and for thicker glasses or thicker PVB (> 0,76 mm) 156o cutting diamonds are used. Cutting diamonds with plastic bodies are used on the laminated glass cutting tables. However 135o diamond with white body, 145o diamond with black body and 156o diamond with red body are widely available on the market, confirmation from the supplier is recommended.
The pressure given to the cutting heads is as important as the proper choice of the cutting diamond. Although minimum and maximum pressure values are declared by the manufacturer for every machine, these values may need to be revised according to the conditions of the glass and the machine.
