MAG HƒÂ¼ller Hille’s new NBH 5+ Speed horizontal machining center is an ideal manufacturing solution for large aluminum parts or tombstones in automotive, electronic and general industrial applications, combining a generous work envelope with a 15,000 rpm motorized spindle, 90 m/min (295 ft/min) linear feeds and 80 rpm B-axis. The machine’s 500 mm (19.7 in) pallet clamping area handles part weights to 800 kg (1,763 lb), while 1G ACC/DEC linear moves, high-speed B-axis and three-second chip-to-chip tool changes ensure highest in-cut times and lowest cost per part. With a compact footprint of just 5.25 m x 5.3 m x 3 m (17.2 x 17.4 x 9.8 ft) the NBH 5+ Speed provides a best-in-class work envelope of 800 mm diameter by 1,000 mm high (31.5 x 39.3 in).
The NBH 5+ Speed features a one-piece cast-iron bed, heavily ribbed for exceptional rigidity and vibration damping. Equipped for HSK63A tool holders, the spindle delivers 35 kW (47 hp) power and 120 Nm (88.5 lb ft) torque in continuous duty. X-Y-Z travels are 890, 800 and 900 mm (35, 31.5, 35.4 in) respectively, on slip-free, pre-tensioned linear guides with integrated scales. Linear positioning accuracy is 0.007 mm (0.0003 in); rotary positioning accuracy is 0.0028 degrees (DIN ISO 230-2). The machine’s Siemens 840D control provides ample processing power for look-ahead to maintain top speeds in curves and contours. Through-spindle coolant at 40 bar, a 134-tool magazine and an integrated spiral chip conveyor provide flexible processing capability and high-volume metal removal capacity.
The NBH 5+ Speed is one of three new HMC models that will be in the MAG Industrial Automation Systems booth, A-8218 at IMTS.
