Niigata HN80E-FC

The Niigata HN80E-FC is a facing center: a horizontal machining center with two tools-in-one at the spindle head. A sliding faceplate, the U axis, does turning-type cuts. Through its centre runs a φ130 feeding spindle, the W axis, which extends 300 mm (11.8 in) for milling, drilling and boring. On an 800 mm × 800 mm pallet carrying 2,500 kg (5,511 lb), the machine can face, groove, taper, bore, mill and drill a part without moving it to another machine.

The W-axis spindle takes BT50 tools, runs to 2,500 min-1 and is rated at 659.5 N·m (486 lb-ft) with an AC 26/22 kW motor. The faceplate takes a separate NT50 short-taper tool and has 130 mm (5.1 in) of U travel. Niigata's twin U spindle option extends that to 230 mm, enough to cover large and small diameters with one tool type and to bring the tool to centre for deep holes.

The base machine is the HN80E, and X and Z keep its travels of 1,530 mm and 1,020 mm and its φ1,750 mm × 1,400 mm workpiece. Y is given as 900 mm (35.4 in), a figure the table ties to the twin U spindle. Rapid rates are set per axis: 40 m/min in X, 25 m/min in Z, 15 m/min in Y and 5 m/min for W and U. This is the fastest of the three FC models in X and Z.

Niigata names fluid ends and axle housings as typical parts. Both have deep bores with faces, grooves and threads at the bottom, which is where a faceplate with a feed-out spindle earns its place. The magazine holds 62 tools, with 88, 128, 175 and 255 as options.
