Price estimate
We do not have a price for the Akira Seiki HV5.5A 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
A 1,500 x 600 mm (59 x 23.6 in) table under a 50-taper spindle: that is the Akira Seiki HV5.5A. X travel is 1,350 mm (53 in), Y is 640 mm (25 in), Z is 660 mm (26 in), and the table is rated for 1,500 kg (3,307 lb) standard and 1,800 kg (3,968 lb) maximum.
It shares its column and saddle with the HV4.5A. The longer X adds little to the machine: weight goes from 8,033 kg (17,710 lb) on the HV4.5A to 8,290 kg (18,276 lb) here, and the footprint to 3,800 x 2,495 mm (150 x 98 in). The coolant tank grows to 400 L (105.7 gal).
The spindle is BT50 / CAT50, 42 HP (31.3 kW) peak with 35 HP (26.1 kW) available for 30 minutes, at 8,000 rpm or an optional 6,000 rpm. Is 8,000 rpm enough? For the face mills, shell mills and indexable drills a 50-taper machine exists to drive, yes. For small end mills in aluminium, no, and the V5.5XP on the same travels is the better fit.
Listed accuracy is 0.01 mm (0.00039 in) positioning and ±0.003 mm (±0.00012 in) repeatability, the tighter of the two accuracy classes in the HV series. Power requirement is 35 kVA. Chips go to a drawer.

Frequently Asked Questions
01
X 1,350 mm (53 in), Y 640 mm (25 in), Z 660 mm (26 in). The table is 1,500 x 600 mm (59 x 23.6 in) with five 18 mm T-slots at 100 mm pitch, and the spindle nose is 100~760 mm (4~30 in) above it.
02
Not much. The HV5.5A weighs 8,290 kg (18,276 lb) and the HV4.5A 8,033 kg (17,710 lb). The two share Y and Z travels and the same spindle; the HV5.5A has the longer X and the larger table rating.
03
42 HP (31.3 kW) peak and 35 HP (26.1 kW) on the 30-minute rating, through a BT50 / CAT50 taper. Maximum speed is 8,000 rpm, or 6,000 rpm as an option. The spindle is oil chilled.
04
A power requirement of 35 kVA and compressed air at 0.5 MPa (72.5 psi). The machine measures 3,800 x 2,495 mm (150 x 98 in) and the coolant tank holds 400 L (105.7 gal).
