The L20 Evolves for the Next Generation of Performance

The CINCOM L20E-IX builds upon it's predecessor, the highly acclaimed L20-VIII, to meet the latest market requirements. The Evolution lineup is Citizen's new product line to provide a solution to the drastically changing needs in the global market.

 

The L20E-IX has been specially developed for high-precision manufacture of simple and complex parts in medium to large batch sizes. It offers all-round versatility and flexibility with its many options and extremely short setup times.

 

Key Features:

  • Latest Generation 'Cincom Control' CNC system

    • Overlapped operations of tool posts - 2 independent tool posts can be moved synchronously to reduce idle periods. For example one toolpost can start work on the next process before the other tool post has fully retracted.

    • Overlapped movements of axes - In a tool replacement or thread cutting operation, axis movements can begin before an operation using another axis has completed. This can greatly reduce idle time.

    • Direct spindle indexing function - the time taken for returning to zero point and spindle indexing are greatly reduced by defining the zero point at which the rotating axis is decelerated and stopped.

    • Smooth acceleration and deceleration with the minimum shock - smoothed acceleration and deceleration operations reduce any shocks transmitted to the machine whilst still enabling fast performance.

  • Increased tool flexibility - Tooling arrangements allow extra cross rotary tools, extra turning tools or extra end-working rotary tools depending on your priorities.

Work Area

Vertical Holder

  • 7 rotary spindles ( 3 can be swiveled 90 deg between cross and end face machining) and 6 turning tools fitted as standard for turning, grooving, screw-cutting, parting-off etc.

  • Standard Y-axis facilitates tool centre height adjustment and enables complex operations to be carried out with ease.

  • Rotary tools rated at 1kW / 5,000RPM.

  • Tooling arrangements allow extra cross rotary tools, extra turning tools or extra end-working rotary tools depending on your priorities.

Front / Back Machining Holders

  • 7 fixed end-working positions (3 front / 4 back) as standard (8 optional 3 front / 5 back).

  • Allows operations such as drilling, tapping, screw-cutting, boring and turning to be carried out simulataneously with other operations.

  • Optionally sub spindle opposed toolpost can be fitted with up to 4 rotary tools (0.4kW, 5,000RPM).

Supporting Software Options

CNC Wizard

Low-cost Programming Aid for Citizen machines for faster and easier part-program creation. The software leads you through creation of your part-program using clear diagrams, photos and text. A simple program can be potentially be written in a matter of minutes! Full editing and communications features are built into the software along with program validation checks. Ideal for both new and experienced Citizen users.

Alarm alerting system

Automatically inform designated people in your organisation if an alarm occurs on one of your Citizen machines. Up to 100 machines can be simultaneously monitored. The message delivery can be via. voice message to land-line or mobile, SMS text message to a mobile or Email. Multiple recipients can be specified for each machine. This system is ideal for those running the machine unattended overnight.
