Cincom A20

For Price, Performance, and Ease of Use...“A” is the New Wave.

Improved Productivity

The approach to improving productivity (that was adopted to customer acclaim with the Cincom K16 and L20) is fully utilized in the A20. By installing the latest NC unit and adopting Citizen’s unique control technique “Streamline Control” we have managed to slash idle time and reduce cycle time. This is a new generation of CNC automatic lathe that, while giving you unrivalled cost performance, also gives a real sense of true productivity improvements.
