Cincom L-720 is the fastest and most efficient seven-axis L20 series Swiss-type lathe ever developed by Citizen. The lathe must be seen to appreciate its speed and tooling flexibility.

This lathe is equipped with the Mitsubishi 700 control. Full servo axes and advanced technologies enable faster machining operations while reducing non-cutting idle time by 40 percent compared to that of earlier L-20 models.

The machine incorporates the new Mitsubishi Meldas 700LC control. This control's mathematical processing capability of the Mitsubishi control combined with the Citizen L-20's mechanical enhancements offers quick and smooth parts manufacturing. This is almost three times faster than the company's earlier conventional machines. Another new control features is the TFT color LCD screen. This new monitor sharpens the image during a specific machining operation of a part and allows greater operator visibility. The instantaneous start up and shut down of the control is another feature.

Two independent tool posts can move at the same time thus reducing non-cutting idle time. For example, one tool post does not need to return to a home position before the other starts its next task. This allows the second tool past to start the next process overlapping the movement of the first.

In an ID/OD tooling operation or thread cutting operation, moving another axis can start without waiting before the movement of the other axis is complete. This process along can reduce wasted time and provide optimum operation by 40 to 50 percent.
