Our best estimate for the Star Micronics SW-12RII is $140,000 - $230,000. This is an estimate for a swiss-type lathes in this class, not a quote from Star Micronics; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/star-micronics-sw-12r-ll#price; the request is passed to Star Micronics or an authorised dealer.
Maximum machining diameter and bar capacity are Ø13 mm (33/64 in). The standard headstock stroke is 135 mm (5-5/16 in), which sets the length that can be turned in one chucking. A maximum part projection of 20 mm (25/32 in) is also listed.
In speed, yes: both are listed at 15,000 rpm. Both also show 2.2 kW continuous and a 3.7 kW short-time figure, but the duty rating differs between the rows. The main spindle row reads 3.7 kW (10min/25%ED) and the sub spindle row reads 3.7 kW (10min./40%ED).
The front post holds 5 turning tools with 2 rear tools, all on 10 mm shanks. A 4-spindle sleeve holder adds 4 front and 4 rear tools. For the sub spindle, the back 8-spindle unit takes a maximum of 8 stationary tools plus 8 power-driven tools.
They vary by axis. X2, Y1, Y3, Z1 and Z2 move at 35 m/min, X1 and X3 at 24 m/min, and Y2 at 15 m/min. The slower axes matter mostly on short-cycle parts, where tool-to-tool positioning is a visible share of the cycle.
The SW-20 is the larger machine: Ø20 mm (25/32 in) bar against Ø13 mm (33/64 in), 10,000 rpm against 15,000 rpm, and 3,400 kg against 2,100 kg. The SW-20 lists the same 2.2 kW (continuous) / 3.7 kW (10min/25%ED) main spindle power, and Front 4 tools / Rear 2 tools where the SW-12RII has front 5 tools and rear 2 tools.
