HULLER HILLE NBH 630 HORIZONTAL MACHINING CENTER

Technical Description

The Hüller Hille NBH 630 is a robust 5-axis horizontal machining center engineered for precision and heavy-duty manufacturing applications. This machine features a compact, one-piece rigid bed with dual X-axis levels, providing exceptional stability during complex machining operations. The working envelope accommodates parts up to 24.803 inches on both pallet width and length dimensions, with travel ranges of 39.37 inches (X-axis), 33.465 inches (Y-axis), and 45.276 inches (Z-axis), enabling versatile workpiece configurations. The machine incorporates a fast 180-degree swivel pallet changer and integrates CNC control via Siemens 840D sl, ensuring synchronized precision positioning and high dynamics across all five controlled axes. The NBH 630 is available with multiple spindle configurations, including motor spindles delivering up to 52 kW and gear spindles producing up to 1,236 Newton-meters of torque at 10,000 rpm, making it ideal for high-volume roughing operations and demanding manufacturing tasks. The thermally symmetrical, optimally ribbed construction minimizes thermal distortion, while the backlash-free direct drive in the B-axis enables simultaneous multi-axis machining with exceptional dimensional accuracy. The machine's modular spindle design allows customization for specific applications, including milling-turning operations and cylindrical gear skiving. Renowned for robustness and reliable long-term performance, the NBH 630 represents Hüller Hille's commitment to delivering extreme power combined with perfect precision for complex workpiece production.
