Machine Comparison
Citizen Cincom L12 Type VII vs Citizen Cincom L12 Type X
Citizen Machinery vs Citizen Machinery · Swiss-Type Lathes
Summary
The Citizen Cincom L12 Type VII and the Citizen Cincom L12 Type X are two versions of Citizen's small Swiss-type lathe, both aimed at precision turned parts of small diameter. Citizen publishes few comparable figures for this pair: the table has two rows.
The Type X has the faster sub-spindle, 12,000 rpm against 10,000 rpm, which helps back-end work on small diameters. The Type VII is the lighter machine at 1,700 kg against 2,200 kg. Beyond that, the published scope differs in emphasis: the Type VII is described for very small high-speed parts, short parts on its guide-bushless GBL build and complex parts with many tools, while the Type X is described for parts with milled or drilled back-end features and long slender work in guide-bush mode.
Specifications Comparison
| Specification | Citizen Cincom L12 Type VII | Citizen Cincom L12 Type X |
|---|---|---|
| Sub-Spindle Speed | 10,000 rpm | max. 12,000 rpm ▲ |
| Machine Weight | 1,700 kg | 2,200 kg |
Advantages
Citizen Cincom L12 Type VII
- Lighter machine at 1,700 kg against 2,200 kg
- Available as a guide-bushless GBL build for short parts
- Described for complex small parts that need many tools
Citizen Cincom L12 Type X
- Sub-spindle to 12,000 rpm against 10,000 rpm
- Aimed at parts with milled or drilled features on the back end
- Long slender parts machined in guide-bush mode
Verdict
For parts whose cycle time is driven by back-end drilling and milling, the Citizen Cincom L12 Type X is the stronger choice, since its sub-spindle runs to 12,000 rpm against 10,000 rpm. For short parts that suit a guide-bushless setup, or where a lighter 1,700 kg machine matters, the Citizen Cincom L12 Type VII fits. With only two published rows to compare, check each machine's tooling layout against the part before deciding.
