How much does the Akira Seiki SL35 cost?
Price estimate
We do not have a price for the Akira Seiki SL35 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
Torque is the story of the Akira Seiki SL35. Its A2-8 spindle delivers 727 Nm (536 lb-ft) at peak, with 30 HP (22.4 kW) and a top speed of 3,500 rpm. The SL30, one size down, has 305 Nm (225 lb-ft). For a 10" chuck lathe, standard here with a 12" option, that is a large step.
Capacity grows more modestly. Maximum cutting diameter is 450 mm (17.7 in), cutting length 600 mm (23.6 in), swing over the bed 650 mm (25.6 in). The draw tube bore is 78 mm (3.1 in), which takes the machine into large-bar work.
So the SL35 is the lathe for heavy cuts on medium-size parts: forgings, flame-cut blanks, tough alloys, large-diameter drilling from solid. X travel is 235 + 20 mm (9.2 + 0.8 in) and Z travel 630 mm (24.8 in). The tailstock, listed as part of the machine, has 630 mm (24.8 in) of travel and an MT4 quill with a 100 mm (3.9 in) stroke.
The turret carries 12 stations, 25 mm (0.98 in) OD tools and 40 mm (1.57 in) boring bars, with a 0.35 s index. The machine weighs 5,600 kg (12,346 lb), measures 3,050 x 1,844 mm (120 x 73 in) and requires 30 kVA. Chip disposal is a drawer as standard, a conveyor as an option.

Strengths & Limitations
Strengths
- 727 Nm (536 lb-ft) of peak spindle torque
- 78 mm (3.1 in) draw tube bore
- 10" chuck standard, 12" optional, on an A2-8 nose
- Tailstock with 630 mm (24.8 in) of travel listed as part of the machine
Limitations
- Top speed of 3,500 rpm limits small-diameter finishing
- Cutting length of 600 mm (23.6 in), the same as the smaller SL30
- 25 mm (0.98 in) OD tools on a lathe with this much torque
- A chip conveyor is optional; a drawer is standard

Frequently Asked Questions
01
727 Nm (536 lb-ft) at peak, with 30 HP (22.4 kW) peak power and a maximum speed of 3,500 rpm. The spindle nose is A2-8.
02
Maximum cutting diameter is 450 mm (17.7 in) and maximum cutting length 600 mm (23.6 in). Swing over the bed is 650 mm (25.6 in) and the draw tube bore 78 mm (3.1 in).
03
A 10" chuck is standard and a 12" chuck is optional. With the 78 mm (3.1 in) bore, the larger chuck suits ring and flange work and the smaller one bar work.
04
Yes, the SL35L, with a 1,000 mm (39.4 in) cutting length and 1,025 mm (40.4 in) of Z travel. The SL35L weighs 7,745 kg (17,075 lb), against 5,600 kg (12,346 lb) for the SL35.
