Star Micronics SB-12R Type G vs Star Micronics SB-16R Type G
Star Micronics vs Star Micronics · Swiss-Type Lathes
Summary
The Star Micronics SB-12R Type G and Star Micronics SB-16R Type G are two sizes of the same Swiss-type platform. They share a 6,000 rpm main spindle rated 2.2 kW continuous (3.7 kW for 10 min), 35 m/min rapids, a Fanuc 0i-TD control and the same 2,070 mm × 1,177 mm × 1,760 mm footprint.
The SB-16R Type G takes bigger bar, Ø16 mm against Ø13 mm. The SB-12R Type G has the faster sub-spindle, 12,000 rpm against 9,000 rpm, which helps on back-working of small diameters. Weights are nearly equal at 1,750 kg and 1,700 kg.

Advantages
Star Micronics SB-12R Type G
- 12,000 rpm sub-spindle against 9,000 rpm
- Aimed at micro screws, implant pins and watch parts under 13 mm, with guide bush flexibility for diverse part families
Star Micronics SB-16R Type G
- Ø16 mm bar capacity against Ø13 mm
- ø16mm maximum turning diameter against 13 mm
Verdict
Pick by the largest bar you run. The Star Micronics SB-16R Type G is the choice for bone screws, sensor housings, fittings and valve parts between 13 mm and 16 mm, on the same footprint and spindle as its smaller sibling. The Star Micronics SB-12R Type G suits micro screws, contact pins and watch parts under 13 mm, where its 12,000 rpm sub-spindle speeds up back-working.
