Our best estimate for the Star Micronics SB-12R Type G is $80,000 - $130,000. 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-sb-12r-type-g#price; the request is passed to Star Micronics or an authorised dealer.
Maximum machining diameter and bar capacity are 13 mm (33/64 in). The next size in the range, the SB-16R Type G, takes Ø16 mm (5/8 in) and is listed at 1,700 kg against 1,750 kg for the SB-12R Type G.
Yes, the table gives a headstock stroke for both modes. With the guide bush the maximum stroke is 205 mm (8 in). Without it the stroke is bar diameter x 2.5, with a maximum of 30 mm, so guide-bushless running is for short parts only.
The turning tool post holds 6 tools with □12 mm shanks or 7 tools with □10 mm shanks. The sleeve holder is a 4-spindle type with 4 tools at the front and 4 at the rear for end-working on the main and sub spindle sides.
Main spindle power is 2.2 kW continuous and 3.7 kW at 10min./25%ED. The sub spindle is rated 0.55 kW continuous and 1.1 kW at 15min./40%ED and is listed at 12,000 rpm. The table lists 6,000 rpm as the main spindle maximum, a figure worth confirming with the dealer because it is half the sub spindle speed.
The footprint is 2,070 mm × 1,177 mm × 1,760 mm and the machine weighs 1,750 kg. Those figures are for the machine alone. A bar feeder adds to the length of the installation and should be laid out with it.
