CITIZEN L20-VIII

The CINCOM L-series 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. All axis movements and even the opening and closing of chucks are implemented by servo motors. As a result, actuation times are reduced by around 50% by comparison with conventional CNC lathes which rely on hydraulics/pneumatics for auxiliary functions. Built-in servo motors require less space and minimise the occurrence of faults.

• Increased driven tool power:
  • The driven tool motor on the gang plate has been upgraded from 0.75kW to 1.0kW.
• Increased Machine Rigidity:
  • Larger and heavier axis slides combined with an improved driven tool clamping system have increased the machine's overall rigidity.
• Increased gang tool post flexibility:
  • Flexibility for more cross-drilling tools - By utilising the triple driven tool spindle (GSE910) the total number of cross-drilling tools can be increased to 7.
  • Increased end-drilling tools - By rotating the GSE910 holder through 90°, 4 cross-drilling tools and 3 front end-drilling tools are possible.
  • Using the double end drilling tool spindle (GSE1007), 4 cross-drilling and front and back end drilling tools are possible.
• Increased tool flexibility:
• You can replace the cross-drilling spindle with a double or triple stationary I.D. tool holder.
• The cross-drilling spindles on T6 and T7 can be switched to turning tools using optional turning tool adaptors.

Citizen's control system makes it possible to control all machine movements simultaneously. By using intelligent servo motors on both axis movements and miscellaneous functions such as opening and closing the collet cycle times are reduced. The elimination of all hydraulics and pneumatics makes machine maintenance easier and increases reliability.

Built-in servo motors allow higher-speed, higher precision and lower noise levels. A new design of servo motor with built-in amplifiers dramatically reduces the space required in the electrical cabinet. Also a modular circuit system results in 50% less wiring and reduced cost.

Supporting Software Options
Remote monitoring and diagnostics	Allows the Service Team to remotely control your machine and provide you with support via. the Internet (if your company has a suitable broadband / leased line connection).
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.
CNC Wizard	Low-cost Programming Aid for Citizen machines to speed-up 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.
CNC Program Editor	An easy-to-use Windows-based CNC program editing system with built-in support for program transfer over RS232 and (optionally) Wireless LAN. Many support functions are included such as code templates for common processes and program validation checks.
