Marubeni Citizen-Cincom Enhances Swiss Turning with Modular Tooling and Flexible Guide Bushing Design!

Marubeni Citizen-Cincom has introduced the Cincom L12 Swiss turning centre, a compact yet highly versatile machine designed to deliver efficient, high-precision machining with enhanced flexibility. Built to meet the evolving needs of manufacturers working with small, complex components, the L12 combines user-friendly programming, modular tooling, and adaptable configurations to optimise productivity across a wide range of applications.

At the core of the Cincom L12 is Citizen’s intuitive programming system, which simplifies complex machining processes through multi-line, multi-axis programming. The system supports superimposed and synchronised control, allowing multiple operations to run simultaneously and reducing overall cycle times. This capability enables operators to handle intricate part geometries with greater ease while maintaining high levels of accuracy and consistency.

One of the standout features of the L12 is its detachable guide bushing, which significantly enhances machining flexibility. When the guide bushing is installed, the machine functions as a traditional Swiss-type automatic lathe, ideal for machining long, slender workpieces with high precision and stability. However, when the guide bushing is removed, the machine can operate in a “non-guide bushing” mode, making it better suited for shorter components. This not only reduces material waste but also improves efficiency for a broader range of part sizes, giving manufacturers greater versatility on a single platform.

The L12 Type X variant builds on these capabilities with additional features designed to further improve performance and usability. A key enhancement is the modular tooling system integrated into both the gang tool post and the back tool post. This system allows for flexible tooling configurations, enabling operators to customise setups based on specific machining requirements. As a result, manufacturers can achieve greater efficiency and reduce setup times when switching between different jobs.

Another important feature is the inclusion of a Y2-axis on the back spindle, which expands the range of machining operations that can be performed on the back side of the component. This added axis increases the machine’s capability to handle more complex parts without requiring secondary operations, thereby improving throughput and reducing handling time.

The machine also incorporates a built-in motor-type back spindle capable of reaching speeds up to 12,000 rpm. This high-speed performance enhances machining efficiency, particularly for operations requiring fine finishes or high precision. Combined with the machine’s optimised structural design—engineered to achieve an ideal balance between strength and weight—the L12 delivers improved rigidity and vibration control, ensuring stable and accurate machining even in demanding conditions.

Overall, the Cincom L12 Swiss turning centre represents a well-balanced solution for manufacturers seeking flexibility, precision, and efficiency in small-part production. By integrating advanced programming, modular tooling, and adaptable configurations, Marubeni Citizen-Cincom continues to support modern manufacturing requirements with innovative and practical machining solutions.
