Machine Comparison
Citizen Cincom A20 vs Hanwha STL-12
Citizen Machinery vs Hanwha · Swiss-Type Lathes
Summary
The Citizen Cincom A20 and the Hanwha STL-12 are both entry-level Swiss-type lathes, and both run the main spindle to 10,000 rpm. The Citizen takes longer parts, with a 200 mm turning length per chucking against the STL-12's 150 mm, and its main spindle is rated 2.2 / 3.7 kW against 2.2 kW.
The Hanwha is faster on the secondary operations: its sub-spindle reaches 10,000 rpm against 8,000 rpm, and its live tools run to 8,000 rpm against the A20's 6,000 rpm. It is also the lighter machine at 1,800 kg against 2,200 kg, and it runs a FANUC 32i-B control where the A20 uses Citizen's own CNC.

Advantages
Citizen Cincom A20
- 200 mm turning length per chucking against 150 mm
- Main spindle rated 2.2 / 3.7 kW against 2.2 kW
- 7 axes including C-axis as standard
Hanwha STL-12
- 10,000 rpm sub-spindle against the A20's 8,000 rpm
- 8,000 rpm live tools against 6,000 rpm
- FANUC 32i-B control, familiar to most programmers
- Lighter machine at 1,800 kg (3,968 lb)
Verdict
For longer, simpler turned parts, the Citizen A20's 200 mm turning length and higher-rated main spindle make it the better fit. For small, feature-heavy parts that spend much of their cycle on back-working and cross-milling, the Hanwha STL-12's faster sub-spindle and live tools matter more, and its FANUC control can shorten training for shops already using FANUC.
