Overview
The Citizen Cincom E25 is a 25mm capacity Swiss-type sliding headstock lathe positioned for precision mid-range bar work where the 20mm class falls short and the 32mm class represents more machine than the application demands. The E25 fills this niche with a capable, cost-effective platform that delivers Citizen's signature accuracy and surface finish in a compact envelope well-suited to high-density production cells.
The E25 configuration combines a gang tool slide for OD turning and a cross-drilling unit for radial features, giving it the versatility to tackle common part geometries found in automotive, pneumatics, and general precision machining without the complexity overhead of a full 6-axis platform. Driven tools are available at multiple positions, enabling milling, drilling, and tapping in a single setup.
Citizen equips the E25 with the same OSP-P300S control found across the Cincom family, ensuring that operators familiar with other Citizen machines face minimal retraining. The control supports both EIA/ISO G-code programming and Citizen's conversational MANUAL GUIDE interface, which is particularly appreciated in shops that rely on experienced operators rather than dedicated CNC programmers. LFV chip-breaking is available as an option, extending the machine's capability into difficult materials.
With its 25mm bar capacity and proven mechanical design, the Cincom E25 is a practical workhorse for shops producing fittings, fasteners, valve bodies, and similar rotational components in the mid-diameter range. Its moderate price point relative to larger Swiss platforms makes it accessible to smaller contract shops seeking to add Swiss capability without a major capital commitment.

Strengths & Limitations
Strengths
- 25mm bar capacity covers a broad range of common fittings and fastener diameters
- Compact footprint suits high-density production cells with limited floor space
- OSP-P300S control familiar to any Citizen operator, minimizing retraining
- Cost-effective entry into the 25mm Swiss class without oversizing to 32mm
- LFV chip-breaking available as option for difficult material work
Limitations
- 5-axis configuration less capable than the 6-axis F20 for complex simultaneous operations
- 28-tool capacity may constrain high-mix operations requiring large tooling arrays
- Not ideal for very complex multi-feature parts that benefit from additional CNC axes

Frequently Asked Questions
01
The E25 and D25 share the 25mm bar capacity but differ in tooling configuration and axis count. The D25 is an older generation model in the Cincom lineup, while the E25 reflects a more current mechanical design with updated control integration. Shops should compare the specific tooling layouts and live tool positions to match their part requirements.
02
Citizen offers GBL conversion for select Cincom models. Availability for the E25 should be confirmed with the regional Citizen distributor, as GBL suitability depends on part length-to-diameter ratio and workpiece material.
03
In guide-bushing mode the E25 can produce parts up to approximately 200mm in length from the collet face. Actual maximum depends on bar diameter and workpiece rigidity.
04
Yes. The E25 handles 303 and 304 stainless steel effectively in standard configuration. For 316L and duplex stainless, enabling LFV chip-breaking is strongly recommended to manage chip control and prevent tool damage.
05
The E25 accepts standard 12-foot bar feeders from LNS, Edge Technologies, and other major suppliers. Citizen can advise on approved feeder configurations for specific bar diameters and material types.
