How much does the Akira Seiki HV6A cost?
Price estimate
We do not have a price for the Akira Seiki HV6A 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
The HV6A is where Akira Seiki's 50-taper line moves to a heavier frame. Against the HV5.5A, weight jumps from 8,290 kg (18,276 lb) to 12,475 kg (27,503 lb) here, and the travels grow in all three axes: 1,630 mm (64.2 in) in X, 850 mm (33.5 in) in Y, 815 mm (32 in) in Z.
The table is 1,750 x 800 mm (69 x 31.5 in), with six 18 mm T-slots at 125 mm pitch. It carries 2,300 kg (5,071 lb) as standard and 2,760 kg (6,085 lb) at most. Daylight under the spindle is 120~935 mm (5~37 in), enough for a tall fixture with a long tool above it.
Nothing changes at the spindle. It is the series' BT50 / CAT50 unit: 42 HP (31.3 kW) peak, 35 HP (26.1 kW) for 30 minutes, 8,000 rpm or an optional 6,000 rpm, oil chilled. What the bigger casting gives that spindle is mass behind the cut and room for the part.
The accuracy class is looser than on the two smaller HV machines, at 0.015 mm (0.00059 in) positioning and ±0.005 mm (±0.00020 in) repeatability. Floor area is 4,300 x 3,525 mm (169 x 139 in). The tank holds 640 L (169 gal), supply is 35 kVA, and chip disposal is a drawer.

Frequently Asked Questions
01
Travels are 1,630 mm (64.2 in), 850 mm (33.5 in) and 815 mm (32 in) in X, Y and Z. The table is 1,750 x 800 mm (69 x 31.5 in). The machine measures 4,300 x 3,525 mm (169 x 139 in) and weighs 12,475 kg (27,503 lb).
02
No. Both are listed at 42 HP (31.3 kW) peak, 35 HP (26.1 kW) for 30 minutes and 8,000 rpm with a BT50 / CAT50 taper. The HV6A is the larger and heavier machine around the same spindle.
03
Yes, the V6XP, which lists the same travels and table as the HV6A with a BT40 spindle at 10,000 rpm (V) or 12,000 rpm (XP) and a 7 kg (15 lb) tool weight limit, where the HV6A takes tools to 15 kg (33 lb).
04
The table lists a drawer for chip disposal and a 640 L (169 gal) coolant tank. On a machine meant for heavy roughing, ask Akira Seiki what conveyor arrangements can be supplied.
