Citizen Cincom B12 vs Citizen Cincom B16
Citizen Machinery vs Citizen Machinery · Swiss-Type Lathes
Summary
The Citizen Cincom B12 and Citizen Cincom B16 are two entry-level Citizen Swiss-type lathes with identical published specs. Both turn up to 12 mm (0.472 in) bar and 135 mm (5.31 in) of length, run the main spindle at 10,000min-1(R.G.B.8,000min-1) with 2.2 kW (3 HP), use a Mitsubishi Meldas control with Citizen software, and weigh 1,150kg.
The difference is in what happens after cut-off. The B16 is the dual-spindle version, aimed at complete-part machining where back-facing, back-boring or chamfered rear ends must be done on the machine. The B12 is the single-spindle version, aimed at simple brass and aluminum pins, contacts and bushings that need no back-working.

Advantages
Citizen Cincom B12
- Simpler single-spindle layout for parts that need no back-end operations
- Aimed at the lowest-entry Citizen Swiss platform for simple round parts
Citizen Cincom B16
- Dual-spindle layout for complete parts with back-facing or back-boring
- Aimed at connector pins with chamfered ends and small medical components needing rear features
- Adds dual-spindle capacity alongside existing B12 or L-series machines
Verdict
The published specs are the same, so the part decides. Choose the Citizen Cincom B16 when parts under 12 mm need rear-end features such as back chamfers or back bores, and must come off the machine complete. Choose the Citizen Cincom B12 for high volumes of simple pins, contacts and bushings where every feature can be cut from the front.
