How much does the Akira Seiki V4.5XP cost?
Price estimate
We do not have a price for the Akira Seiki V4.5XP 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 Akira Seiki V4.5XP puts the V-series spindle on the wider of the maker's two mid-size castings. Y travel is 640 mm (25 in), Z is 660 mm (26 in) and X is 1,150 mm (45.3 in). The table, at 1,300 x 600 mm (51.1 x 23.6 in), is 600 mm deep, and the T-slot pitch opens up to 100 mm.
Depth is the reason to buy it. Die sets, mould plates and box-shaped housings need Y and daylight more than X, and this machine offers 100~760 mm (4~30 in) between spindle nose and table. Table load is 1,300 kg (2,866 lb) standard, 1,560 kg (3,439 lb) maximum.
The same envelope exists in the lighter SR45 XP with an 18 HP (13.4 kW) spindle. Here the V version has 30 HP (22.4 kW) peak at 10,000 rpm and the XP version 35 HP (26.1 kW) at 12,000 rpm, and an 8,000 rpm spindle is listed as an option. For mould steel that extra power is the point of the model.
Tooling runs from a 28T arm changer: 65 mm (2.6 in) diameter, 130 mm (5.1 in) with empty neighbours, 250 mm (9.8 in) long, 7 kg (15 lb), 2.2 s per change. Coolant capacity is 350 L (92.5 gal). Supply is 30 kVA.

Strengths & Limitations
Strengths
- 640 mm (25 in) of Y and 660 mm (26 in) of Z travel
- 1,300 x 600 mm (51.1 x 23.6 in) table rated to 1,560 kg (3,439 lb) maximum
- 30 HP (22.4 kW) V or 35 HP (26.1 kW) XP spindle
- Up to 760 mm between spindle nose and table
Limitations
- BT40 only, on a table that carries 1,560 kg (3,439 lb)
- Tools heavier than 7 kg (15 lb) are outside the changer's limit
- The maker prints two unlabelled rapid-feed rows, so axis speed needs confirming
- 350 L (92.5 gal) coolant tank is no larger than on the V3XP

Frequently Asked Questions
01
1,150 mm (45.3 in) in X, 640 mm (25 in) in Y and 660 mm (26 in) in Z. The table is 1,300 x 600 mm (51.1 x 23.6 in) with five 18 mm T-slots at 100 mm pitch.
02
The travels and table size are the same. The SR45 XP has an 18 HP (13.4 kW) spindle at 11,000 rpm and 24T. The V4.5XP has a 30 HP (22.4 kW) or 35 HP (26.1 kW) spindle and 28T, so it removes metal faster on the same parts.
03
Yes, an 8,000 rpm spindle is listed as an option beside the 10,000 rpm V and 12,000 rpm XP spindles. The table gives no power or torque figure for the option, so request the motor curve.
04
Positioning accuracy is listed at 0.01 mm (0.00039 in) and repeatability at ±0.003 mm (±0.00012 in). Those are the same values the maker gives for the smaller V-series machines.
