How much does the Niigata HN1250-S BAR cost?
Price estimate
We do not have a price for the Niigata HN1250-S BAR that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Long workpieces with deep bores are the brief for the Niigata HN1250-S BAR. This horizontal machining center has a rectangular 1,250 mm × 1,000 mm pallet, a bar spindle with 555 mm (21.9 in) of W-axis stroke, and room for a part of φ2,500 mm × 2,000 mm.
X travel is 2,200 mm (86.6 in), Y is 1,650 mm (65.0 in) and Z is 1,200 mm (47.2 in). All three rapid at 41 m/min. The Y figure is lower than on the HN1250-S machining center, which has 1,800 mm; the swing and height of the workpiece are unchanged.
One figure runs the other way. The table rates this pallet at 3,500 kg (7,716 lb), with 5,000 kg (11,023 lb) as an option. That is the same as the HN1000-S BAR and higher than the load Niigata lists for the HN1250-S without the bar spindle. Buyers comparing the two should ask Niigata to confirm the ratings.
The spindle gives 1,836 N·m (1,354 lb-ft) at speeds up to 3,500 min-1 through a BT50 shank. Niigata describes the bar spindle as φ130mm in diameter, with core cooling. Its arguments for the layout are about stiffness and heat: the column feeds without overhang, so the quill rarely has to be run far out, and the spindle sits in the middle of a double column with two Y-axis guides so that heat distorts the structure symmetrically. Two pallet changers are standard. Pallet indexing is 1°, with 0.001° as an option, and the magazine holds 62 tools before options.

Strengths & Limitations
Strengths
- Rectangular 1,250 mm × 1,000 mm pallet combined with a 555 mm (21.9 in) bar spindle stroke
- Workpiece up to φ2,500 mm × 2,000 mm
- 41 m/min rapids on X, Y and Z
- 3,500 kg (7,716 lb) pallet load, 5,000 kg (11,023 lb) optional

Frequently Asked Questions
01
1,250 mm × 1,000 mm. The maximum mass on the pallet is 3,500 kg (7,716 lb), with 5,000 kg (11,023 lb) as an option, and the maximum workpiece is φ2,500 mm in swing by 2,000 mm in height.
02
X is 2,200 mm, Y is 1,650 mm, Z is 1,200 mm and the W axis of the bar spindle is 555 mm. Rapid traverse is 41 m/min on X, Y and Z and 5 m/min on W.
03
The BAR model has the bar spindle with a 555 mm W axis, rated 1,836 N·m at 3,500 min-1. The HN1250-S has a 6,000 min-1 machining spindle with 1,200 N·m and 37 kW as standard, and 1,800 mm of Y travel. Pallet size, X and Z travels and rapids are shared.
04
For thermal symmetry. Niigata says the double column and center spindle form a thermally symmetrical structure, and that a double guide system on the Y axis reduces the effects of thermal displacement. The rigidity of the column is also cited for precision.
