How much does the Akira Seiki SR42 XP cost?
Price estimate
We do not have a price for the Akira Seiki SR42 XP 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
One metre of X is the dividing line for a lot of shop work, and the Akira Seiki SR42 XP sits just past it at 1,050 mm (41.3 in). Y is 540 mm (21.3 in), Z is 560 mm (22 in), and the table measures 1,200 x 480 mm (47.2 x 19 in).
This is the middle of three machines on one frame. The SR32 XP has 815 mm (32.1 in) of X and the SR52 XP has 1,300 mm (51.2 in); all three share the Y and Z travels, the 18 HP (13.4 kW) BT40 spindle at 11,000 rpm, the 24T magazine and the 30 / 30 / 25 m/min (1,181 / 1,181 / 984 ipm) rapids. So the question to settle is how long the parts are, or how many vises the job needs in a row.
Table load is 980 kg (2,161 lb) standard and 1,176 kg (2,593 lb) maximum. Tools can be 80 mm (3.2 in) in diameter with full pockets, 150 mm (5.9 in) with empty neighbours, 250 mm (9.8 in) long and 7 kg (15 lb). The tool change takes 2.2 s.
On the floor the machine occupies 3,370 x 2,240 mm (133 x 88 in). It draws 30 kVA, needs 0.5 MPa (72.5 psi) air, and carries 350 L (92.5 gal) of coolant with a chip screw for swarf.

Frequently Asked Questions
01
1,050 mm (41.3 in). Y travel is 540 mm (21.3 in) and Z travel 560 mm (22 in). The table itself is 1,200 x 480 mm (47.2 x 19 in), so it is longer than the X stroke.
02
The SR45 XP is wider and taller: 1,150 mm (45.3 in) of X, 640 mm (25 in) of Y and 660 mm (26 in) of Z on a 1,300 x 600 mm (51.1 x 23.6 in) table. The SR45 XP table also takes more, 1,560 kg (3,440 lb) at most against 1,176 kg (2,593 lb) here. Spindle and magazine are the same.
03
24T. Maximum tool diameter is 80 mm (3.2 in), or 150 mm (5.9 in) without a neighbouring tool. Maximum length is 250 mm (9.8 in) and maximum weight 7 kg (15 lb).
04
The maker lists positioning at 0.01 mm (0.00039 in) and repeatability at ±0.003 mm (±0.00012 in). The table does not say which standard those figures were measured to.
