Knuth PORTALO B 1810 VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a robust table measuring 75.000 inches in length by 39.000 inches in width, capable of supporting workpieces up to 19,800 lbs, making it suitable for heavy-duty machining applications. The machine offers optional support for index and rotary tables, enhancing its versatility for complex part setups. The vertical spindle utilizes a BT 50 taper, delivering high rigidity and precision for demanding milling operations, with a maximum spindle speed of 8,000 RPM. The spindle is powered by a 24.1 HP motor (30-minute rating), with an optional 16.09 HP configuration available for different machining needs. Tooling is managed by a 20-station automatic tool changer, enabling rapid tool-to-tool changeover in just 6 seconds, and a pallet changer is available as an option for increased productivity. The machine operates on three primary axes (X, Y, Z), with travel distances of 41.300 inches (X), 79.000 inches (Y), and 22.000 inches (Z). Maximum feed rates and rapid traverse speeds are both set at 591 inches per minute for X, Y, and Z axes, ensuring efficient material removal and quick positioning. The design supports high-speed, high-accuracy machining for a wide range of industrial applications, including aerospace, automotive, and heavy machinery, with the ability to handle large, heavy workpieces and complex geometries.
