Star Micronics vs Star Micronics · Swiss-Type Lathes
Summary
The Star Micronics SL-10 and the Star Micronics SK-51 Type A are in very different size classes and serve different jobs. The SL-10 turns bar up to 10 mm (25/64 in) and weighs 1,600 kg. The SK-51 Type A takes bar up to 51 mm (2 in) and weighs 6,600 kg. Both run a FANUC 32i-B control.
The SK-51 Type A has twice the spindle power, 7.5 kW continuous and 11 kW on the 15-minute rating against 3.7 kW continuous and 5.5 kW on the 10-minute rating, and its tool capacity is listed at 12 against 6 tools. The SL-10 has the faster sub-spindle, 9,000 rpm against 5,000 RPM, and a far smaller footprint: 1,865 × 795 mm against 2,800 x 2,070 mm.
