How much does the Akira Seiki SL15 cost?
Price estimate
We do not have a price for the Akira Seiki SL15 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 SL15 is the smallest turret lathe in the SL two-axis range, set up as a collet machine. The chuck row lists a CR42 or 5C collet, the draw tube bore is 42 mm (1.7 in), and maximum cutting length is 200 mm (7.9 in). Maximum cutting diameter is 290 mm (11.4 in) under a 450 mm (17.7 in) swing.
It shares its headstock with the SL20: A2-5 nose, 6,000 rpm, 24 HP (17.9 kW) and 137 Nm (101 lb-ft) at peak. That is a strong spindle for bar work of this diameter, and it means the SL15 can take real cuts in steel instead of only skimming.
The turret has 10 stations and indexes in 0.5 s. OD tools are 20 mm (0.79 in) square and boring bars 25 mm (0.98 in). X travel is 150 + 15 mm (5.9 + 0.59 in) and Z travel 220 mm (8.7 in), with rapids of 36 m/min (1,417 ipm).
No tailstock is listed for this model; the SL20, with 350 mm (13.8 in) of Z, is the version with one. So the SL15 suits short chucking and bar parts that do not need support. It weighs 2,500 kg (5,512 lb) and needs 20 kVA. The coolant tank holds 120 L (32 gal), with a chip drawer as standard and a conveyor as an option. The control is the AKIRA Mi:845.
