Max. panel dimension (without lifting table feeding): 5800x2010 mm. Safety device according to CE: included. Supply voltage: 400 V / 50 Hz. MACHINE CONFIGURATION. Machine bed: The machine bed structure made of steel is welded using arc welding and then milled and finished on CNC machines. The rigid structure of the machine bed guarantees both high cutting quality with high cutting speed, as well as the enormous durability of the entire machine. Saw blade overhang: 100 mm. Power of main saw motor: 7.5 kW. Power of scoring saw motor: 2.2 kW. Diameter of main saw blade: 400 mm. Diameter of scoring saw blade: 215 mm. Feed rate of saw carriage: Forward: 1-170 m/min. Return: 170 m/min. Motorization of saw carriage feed: Servo drive. Diameter of dust extraction port (bottom, 1x): 200 mm. Diameter of dust extraction port (top, 2x): 115 mm. Thanks to the rigid machine bed construction, the masses are distributed in the best possible way, which prevents twisting and thus guarantees an absolutely vertical run of the saw blade. Machine table made of steel with individual, removable support elements made of high-quality, durable material. The saw carriage runs on two round guides, which are mounted horizontally on one level. Large prism rollers (diameter 86 mm), with spring-loaded counter rollers, ensure smooth linear feed, as well as very low contact pressure and enables virtually wear-free operation of the saw carriage. The weight and forces acting on the saw carriage are evenly distributed on the two guides (50/50) and on each individual prism roller. The saw carriage runs absolutely without lubricant on the guides. The two guides are located away from the cutting line, outside the direct dust area. The diameter of the guide rods is 40 mm, making them the largest and most stable guides used in this sector. Pneumatic quick clamping system; for quick and convenient tool changes. This system is extremely reliable in operation, as it is mechanically clamped via a flange with a bayonet lock and spring force and unlocked via a pneumatic quick coupling. The flange must be rotated by approx. 10° in order to remove it. Due to excellent accessibility and the fact that the operator does not need any other tools, the tool change is very easy and can be carried out in seconds. The scoring saw adjustment is made from the outside. Credpfx Aqezn N Ikegsf
