How much does the Akira Seiki SL35L cost?
Price estimate
We do not have a price for the Akira Seiki SL35L 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 SL35L combines the high-torque SL35 headstock with a one-metre bed. Maximum cutting length is 1,000 mm (39.4 in), Z travel 1,025 mm (40.4 in), and the spindle still delivers 727 Nm (536 lb-ft) and 30 HP (22.4 kW) at peak through an A2-8 nose.
Long parts and heavy cuts together are hard on a lathe, and the bed has been built up to suit. The SL35L weighs 7,745 kg (17,075 lb), which makes it the heaviest machine in the two-axis SL line, heavier even than the larger-swing SL40L at 7,700 kg (16,976 lb). Footprint is 3,450 x 1,844 mm (135.8 x 73 in).
Workholding is a 10" chuck with a 12" option, over a 78 mm (3.1 in) draw tube bore. Maximum cutting diameter is 450 mm (17.7 in). Top speed is 3,500 rpm. The quill is MT4 with a 100 mm (3.9 in) stroke; the maker's tailstock-travel row for the long bed has a misprinted figure and is not shown on this page.
Typical work would be heavy shafts, rolls and long forgings in steel, where a metre of length has to be roughed at depth and then finished between centres. The turret has 12 stations and indexes in 0.35 s, with 25 mm (0.98 in) OD tools and 40 mm (1.57 in) boring bars. Power requirement is 30 kVA.

Frequently Asked Questions
01
Maximum cutting diameter 450 mm (17.7 in), maximum cutting length 1,000 mm (39.4 in), swing over bed 650 mm (25.6 in), Z travel 1,025 mm (40.4 in) and X travel 235 + 20 mm (9.2 + 0.8 in).
02
7,745 kg (17,075 lb), with dimensions of 3,450 x 1,844 mm (135.8 x 73 in). The standard-bed SL35 weighs 5,600 kg (12,346 lb).
03
Yes. Both list 3,500 rpm, 30 HP (22.4 kW) peak and 727 Nm (536 lb-ft) peak torque on an A2-8 nose, with a 78 mm (3.1 in) draw tube bore.
04
A tailstock with an MT4 quill and 100 mm (3.9 in) of quill travel. The travel of the tailstock body is misprinted in the maker's table for the long bed, so ask Akira Seiki for that figure.
