Hanwha STL-12 vs Hanwha XD20H
Hanwha vs Hanwha Precision Machinery · Swiss-Type Lathes
Summary
The Hanwha STL-12 and the Hanwha XD20H are both Swiss-type lathes from the same maker, and both run the main spindle to 10,000 rpm with live tools at 8,000 rpm. The headline difference is capacity: the XD20H takes 20 mm (0.787 in) bar against 12 mm (0.472 in) and turns 210 mm (8.27 in) per chucking against 150 mm (5.91 in).
The XD20H also carries the stronger main spindle, 3.7 kW (5 HP) against 2.2 kW (3.0 hp), and lists a C-axis alongside its 5 axes. The STL-12 answers with a faster sub-spindle, 10,000 rpm against 8,000 RPM, and a newer FANUC 32i-B control where the XD20H runs a Fanuc 18iTB.

Advantages
Hanwha STL-12
- 10,000 rpm sub-spindle against 8,000 RPM for faster back-working
- FANUC 32i-B control against the older Fanuc 18iTB
- Y-axis available as an option on the 5-axis standard build
Hanwha XD20H
- 20 mm (0.787 in) bar capacity against 12 mm (0.472 in)
- 210 mm (8.27 in) maximum turning length against 150 mm (5.91 in)
- 3.7 kW (5 HP) main spindle against 2.2 kW (3.0 hp)
- C-axis listed alongside its 5 axes
Verdict
Choose the Hanwha STL-12 for small-diameter pins, contacts and miniature parts within its 12 mm (0.472 in) bar capacity, where its 10,000 rpm sub-spindle keeps back-working quick and the FANUC 32i-B control is a current platform. Choose the Hanwha XD20H when parts run up to 20 mm (0.787 in) in diameter or 210 mm (8.27 in) long, or when brass, aluminum and mild steel connectors need the extra 3.7 kW (5 HP) at the main spindle.
