CITIZEN CINCOM A20 VIPL CNC lathe

CITIZEN CINCOM A20 VIPL CNC lathe built in 2006 ensures the highest precision and efficiency in the production process. During machining, the specially designed bed with its rigid structure and high thermal stability effectively reduces the heat impact, resulting in increased machine life and reliability. All of this, combined with a modular design with a reduced number of parts, makes the CINCOM A20 VIPL CNC lathe ideal for various types of production.

Workpieces with a maximum diameter of 20 mm and a length of 135 mm are machined in 7 axes by a powerful main spindle which is synchronised with an AC motor, forming an electrospindle. A bushing driven by a separate AC motor is also synchronised with the machine’s main spindle. The operator’s panel consists of an intuitive FANUC 32i CNC controller, a memory card slot and an electronic wheel located next to the monitor designed to check programmes at any speed.

The lathe is offered with a wide range of equipment, including a sub-spindle, driven tools and an LNS Express 220 bar feeder. The machine was in operation for only 69 hours. The CITIZEN swiss type lathe weighs 2300 kg.
