Machine Comparison
Hanwha STL-12 vs INDEX C100
Hanwha vs INDEX-Traub · Swiss-Type Lathes
Summary
The Hanwha STL-12 and the INDEX C100 are both listed as Swiss-type lathes, but they serve different jobs. The STL-12 is a small machine for 12 mm (0.472 in) bar; the INDEX C100 takes 42 mm (1.7 in) bar, turns up to 400 mm against 150 mm (5.91 in), and carries a 25 / 29 kW main spindle against 2.2 kW (3.0 hp).
The STL-12 is the faster machine for small diameters, with main and sub-spindles at 10,000 rpm against 7,000 rpm. Live tools run to 8,000 rpm on both. The INDEX is a far bigger installation at 5,700 kg (12,566 lb) and 5,990 × 1,706 × 2,138 mm, against 1,800 kg (3,968 lb) and 1,900 x 1,200 mm for the Hanwha.

Advantages
Hanwha STL-12
- 10,000 rpm main and sub-spindles against 7,000 rpm
- 1,800 kg (3,968 lb) machine against 5,700 kg (12,566 lb)
- 1,900 x 1,200 mm (74.8 x 47.2 in) floor space against 5,990 × 1,706 mm
INDEX C100
- 42 mm (1.7 in) bar capacity against 12 mm (0.472 in)
- 400 mm maximum turning length against 150 mm (5.91 in)
- 25 / 29 kW main spindle against 2.2 kW (3.0 hp)
- Choice of Siemens S840D sl or FANUC 31i-B control
Verdict
Pick by part diameter. The Hanwha STL-12 is built for high-volume pins, contacts and small medical screws within 12 mm (0.472 in) bar, where 10,000 rpm spindles and a compact 1,800 kg machine make sense. The INDEX C100 belongs in production shops turning complex automotive, medical and aerospace parts up to 42 mm (1.7 in) bar and 400 mm long, where a 25 / 29 kW spindle and simultaneous machining justify a 5,700 kg installation.
