How much does the Akira Seiki SL40LMC cost?
Price estimate
We do not have a price for the Akira Seiki SL40LMC 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 SL40LMC is the largest turning machine Akira Seiki lists with driven tools: a long-bed, geared-head lathe with a C axis. Cutting length is 1,380 mm (54.3 in), Z travel 1,450 mm (57.1 in), and the tailstock travels the same 1,450 mm (57.1 in) on an MT5 quill.
At this length, re-clamping a part for milling is slow and risky, which is the argument for the MC turret. Driven tools run at up to 4,000 rpm with 3.7 kW (5.5 HP) on a BMT65 interface, enough to drill and tap flange holes, mill keyways and cut flats on a shaft that stays between chuck and centre throughout.
The spindle is built for large, tough work: 2,944 Nm (2,171 lb-ft) of peak torque through a gear box, 60 HP (44.7 kW) peak, 2,500 rpm, A2-11 nose. A 15" chuck is standard and an 18" chuck optional. The draw tube bore is 103 mm (4.1 in), maximum cutting diameter 550 mm (21.7 in) and swing over the bed 750 mm (29.5 in).
Some caution about the source is due. The maker's page leaves the long-bed weight cell empty and prints dimensions whose metric and inch figures disagree, so neither appears here. The page URL and heading also spell the model with a letter O. Power requirement is 35 kVA; rapid feed is 30 m/min (1,181 ipm) in X and 36 m/min (1,417 ipm) in Z.

Frequently Asked Questions
01
Maximum cutting length is 1,380 mm (54.3 in) and Z travel 1,450 mm (57.1 in). Maximum cutting diameter is 550 mm (21.7 in) and X travel 285 + 25 mm (11.2 + 1 in).
02
A 12-station BMT65 turret with power tooling rated 3.7 kW (5.5 HP) at up to 4,000 rpm, working with a C axis on the main spindle. The application row lists X+Z+C.
03
The SL40L has no C axis or driven tools and a slightly longer cutting length of 1,500 mm (59 in). The SL40LMC adds milling capability; the headstock, chuck and bore are the same on both.
04
A power requirement of 35 kVA is listed. Chip disposal is a drawer as standard with a conveyor as an option. Weight and floor space should be requested from Akira Seiki.
