Hanwha STL-12 vs Tornos DECO 20a
Hanwha vs Tornos · Swiss-Type Lathes
Summary
The Hanwha STL-12 and the Tornos DECO 20a are Swiss-type lathes that share 10,000 rpm main and sub-spindle speeds. The DECO 20a is the larger machine: 20.5 mm (0.807 in) bar against 12 mm (0.472 in), 200 mm (7.87 in) turning length against 150 mm (5.91 in), and a 5.5 kW (7.4 hp) spindle against 2.2 kW (3.0 hp).
The Tornos also offers up to 10 axes against 5 standard on the STL-12, for more complex parts in one cycle. The STL-12 counters with a lighter frame, 1,800 kg (3,968 lb) against about 3,200 kg (7,055 lb), and a FANUC 32i-B control where the DECO uses Tornos TB-DECO / TISIS programming.

Advantages
Hanwha STL-12
- Lighter machine at 1,800 kg (3,968 lb) against 3,200 kg (7,055 lb)
- FANUC 32i-B control, familiar to most programmers
- Simpler 5-axis standard build, with Y-axis optional
Tornos DECO 20a
- 20.5 mm (0.807 in) bar capacity against 12 mm (0.472 in)
- 200 mm (7.87 in) turning length against 150 mm (5.91 in)
- 5.5 kW (7.4 hp) main spindle against 2.2 kW (3.0 hp)
- Up to 10 axes against 5 standard
Verdict
The Hanwha STL-12 is the choice for small, high-volume parts within 12 mm (0.472 in) bar, such as connector pins and miniature hardware, where a FANUC control and a 1,800 kg machine keep things simple. The Tornos DECO 20a fits medical, watch and connector work that needs up to 20.5 mm (0.807 in) bar, up to 10 axes and a 5.5 kW (7.4 hp) spindle to finish complex parts complete.
