Advantages
Citizen Cincom A20
- 20 mm (25 option) turning diameter against 12 mm (0.472 in)
- 200 mm turning length per chucking against 135 mm (5.31 in)
- Main spindle rated 2.2 / 3.7 kW against 2.2 kW (3 HP)
Citizen Cincom B12
- Lighter machine at 1,150kg against 4,851 lb (2,200 kg)
- Aimed at simple brass and aluminum pins, contacts and bushings in tight floor space
Verdict
Choose the Citizen Cincom A20 when parts run up to 20 mm (25 option) in diameter or need up to 200 mm of turning length, as with connector pins, shafts and second-machine part families. Choose the Citizen Cincom B12 for high volumes of simple round parts under 12 mm, such as pins, contacts and bushings, where a lighter machine in a small footprint is enough.
