How much does the Akira Seiki SL30SMC cost?
Price estimate
We do not have a price for the Akira Seiki SL30SMC 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 SL30SMC is the sub-spindle lathe of the SL family. The application row lists X+Z+B+C: turning axes, a C axis, and a B axis that carries the second spindle along the bed to take the part from the main chuck. With driven tools in the turret, a part can be turned and milled on both ends and dropped complete.
The maker's table prints two figures in each spindle row without labelling them. They read 4,500 rpm / 6,000 rpm for speed, 24 HP (17.9 kW) / 24 HP (17.9 kW) for peak power, 305 Nm (225 lb-ft) / 124 Nm (91 lb-ft) for peak torque, A2-6 / A2-5 for the nose and 65 mm (2.6 in) / 31 mm (1.2 in) for the draw tube bore. The first of each pair matches the SL30MC main spindle, so the second is presumably the sub-spindle; confirm that reading with Akira Seiki.
Capacity is a 400 mm (15.7 in) maximum cutting diameter and a 750 mm (29.5 in) cutting length, with 850 mm (33.5 in) of Z travel. The 12-station turret is BMT65 with ER32 live holders, driven tools at 4,000 rpm, and turret power listed for S1 / S2 as 2.2 kW / 3.7 kW. Index time is 0.57 s.
No tailstock is listed, as the second spindle takes its place. The machine weighs 7,000 kg (15,432 lb), measures 3,630 x 1,910 mm (143 x 75.2 in) and needs 45 kVA, the highest supply figure in the SL range.

Strengths & Limitations
Strengths
- Sub-spindle for machining both ends in one cycle (X+Z+B+C)
- BMT65 turret with driven tools at 4,000 rpm
- 400 mm (15.7 in) cutting diameter and 750 mm (29.5 in) cutting length
- 850 mm (33.5 in) of Z travel
Limitations
- The maker's table does not label which spindle each paired figure belongs to
- Power requirement of 45 kVA
- No tailstock, so long slender shafts lack centre support
- No Y axis is listed in the application row

Frequently Asked Questions
01
It takes the part from the main spindle so the back end can be machined in the same cycle. The application row lists X+Z+B+C, and the page's short description is Sub-Spindle: Performa High Speed Turning.
02
The table prints pairs: 4,500 rpm / 6,000 rpm, 24 HP (17.9 kW) / 24 HP (17.9 kW), 305 Nm (225 lb-ft) / 124 Nm (91 lb-ft) and A2-6 / A2-5. It does not say which is the main and which the sub-spindle.
03
A 12-station BMT65 turret with ER32, power tooling at up to 4,000 rpm and turret power listed as 2.2 kW / 3.7 kW for S1 / S2. Tool change time with a neighbouring tool is 0.57 s.
04
3,630 x 1,910 mm (143 x 75.2 in), at 7,000 kg (15,432 lb). The power requirement is 45 kVA, and a chip drawer is standard with a conveyor optional.
