How much does the Akira Seiki SR3 XP cost?
Price estimate
We do not have a price for the Akira Seiki SR3 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
The Akira Seiki SR3 XP is the 30-inch member of the small SR frame: 762 mm (30 in) of X travel, 430 mm (16.9 in) of Y and 460 mm (18.1 in) of Z. Its table is 910 x 380 mm (36 x 15 in), long and narrow, which suits vises set side by side along X.
Everything above the table is shared with the SR2 XP. The BT40 spindle turns 11,000 rpm on 15 HP (11.2 kW) peak, the magazine holds 20T, and rapids are 36 / 36 / 30 m/min (1,417 / 1,417 / 1,181 ipm). What changes is length. The machine is 2,600 x 1,935 mm (102 x 76 in) on the floor, and table load climbs to 660 kg (1,455 lb) standard and 792 kg (1,746 lb) maximum.
Is the narrow Y a problem? For plate work and mould bases it can be. The SR32 XP is the next step when it is: 540 mm (21.3 in) of Y and a 950 x 480 mm (37.4 x 19 in) table, on a heavier frame that needs 30 kVA instead of 20 kVA.
Positioning is listed at 0.01 mm (0.00039 in) and repeatability at ±0.003 mm (±0.00012 in). The control is the AKIRA Mi:845 (Fanuc G code compatible), and chips are cleared by chip screw.

Strengths & Limitations
Strengths
- 762 mm (30 in) of X travel with a 910 x 380 mm (36 x 15 in) table
- Table takes up to 792 kg (1,746 lb)
- 36 / 36 / 30 m/min (1,417 / 1,417 / 1,181 ipm) rapids
- Still a 20 kVA machine at 2,600 x 1,935 mm (102 x 76 in)
Limitations
- Y travel stays at 430 mm (16.9 in) while X grows to 762 mm (30 in)
- The table is only 380 mm deep, so wide plates overhang
- 15 HP (11.2 kW) peak, where the SR32 XP offers 18 HP (13.4 kW)
- 150 L (39.6 gal) coolant capacity

Frequently Asked Questions
01
910 x 380 mm (36 x 15 in), with 16 mm T-slots at 80 mm pitch, four of them. Standard loading is 660 kg (1,455 lb) and maximum loading 792 kg (1,746 lb).
02
The SR32 XP is a larger frame with 815 mm (32.1 in) of X, 540 mm (21.3 in) of Y and 560 mm (22 in) of Z, an 18 HP (13.4 kW) spindle and 24T. The SR3 XP keeps 430 mm (16.9 in) of Y, 15 HP (11.2 kW) and 20T, but its rapids are faster.
03
The spindle is BT40 with a maximum speed of 11,000 rpm and 15 HP (11.2 kW) of peak power. That speed covers most steel and aluminium work with standard 40-taper holders.
04
The table lists a power requirement of 20 kVA and an air pressure requirement of 0.5 MPa (72.5 psi). Floor space is 2,600 x 1,935 mm (102 x 76 in).
