How much does the Akira Seiki SL25MC cost?
Price estimate
We do not have a price for the Akira Seiki SL25MC 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 SL25MC is the smallest lathe in the SL Mill-Turn group. Its application row reads X+Z+C: a two-axis turning center with a C axis on the spindle and driven tools in the turret, so cross holes, flats and keyways can be machined without a second setup.
The driven tools run to 5,000 rpm with 3.7 kW (5.5 HP) at the turret. That is the fastest power-tool speed among the X+Z+C models; the SL30MC and the larger machines are listed at 4,000 rpm. The turret is a 12-station unit with VDI30 tooling and ER25 collets for the live holders, and it indexes in 0.52 s.
Turning capacity is a 530 mm (20.9 in) swing, a maximum cutting diameter of 280 mm (11 in) and a cutting length of 380 mm (15 in). The spindle is the SL25 unit: A2-6 nose, 5,000 rpm, 17 HP (12.7 kW) and 202 Nm (149 lb-ft) at peak, with a 52 mm (2 in) draw tube bore. X travel is 195 + 5 mm (7.6 + 0.2 in) and Z travel 435 mm (17.1 in).
The tailstock is an option here, with 410 mm (16.1 in) of travel and a 100 mm (3.9 in) quill. The machine weighs 4,050 kg (8,929 lb), measures 2,450 x 1,500 mm (97 x 59 in) and needs 30 kVA. The chuck row on the maker's page carries a typing error and is not shown; the two-axis SL25 lists an 8" chuck.
