Niigata HN-80C HORIZONTAL MACHINING CENTER

Technical Description

The 1993 Niigata HN-80C Horizontal Machining Center is a robust CNC machine designed for precision horizontal milling with large workpieces. It features dual pallets measuring 800 mm by 800 mm (31.5" x 31.5") each, supporting a maximum pallet load capacity of approximately 3,300 lbs (1500 kg). The machine offers a substantial working envelope with axis travels of 50.0" on the X-axis, 40.2" on the Y-axis, and 36.2" on the Z-axis. Its spindle, powered by a 35 HP motor, delivers speeds up to 4,500 rpm with a CAT50 taper, accommodating a tool magazine with capacity for 60 tools or more, including tool lengths of up to 21.7" and tool weights up to 66 lbs. Capable of handling a maximum part swing diameter of 68.9", which extends to 78" when the pallet door is open, the HN-80C supports versatile and large-scale machining. The machine is equipped with a Fanuc CNC control system (Series 15-MG or 18iM), facilitating 360-degree pallet indexing with a minimum indexable angle of 1°, rigid tapping, through-spindle coolant, and an automatic tool changer. Rapid traverse rates reach up to 709 inches per minute on all axes. The machine’s footprint is approximately 285" long by 185" wide by 148" high, and it weighs around 42,000 to 48,000 lbs, reflecting its solid industrial build. Ancillary features include a chip conveyor and an automatic pallet changer with two rotary positions, supporting high productivity in heavy-duty manufacturing environments.
