Cincom K16 VII

Introducing the newest generation machine by Citizen. The K-series CNC Automatic Swiss-Type Lathe.

New Fanuc FS31i control

Control system built in with the machine provides a streamline compact appearance. The K-series was also developed to enhance machine performance offering a quick and smooth part process.

Tool post Overlap Operation

Two independent tool posts can move at the same time in the same direction, reducing non-cutting idle time. For example, a tool post does not need to wait to return to a waiting position while the other tool post starts the next process.
Axes overlap

In any thread cutting operation, moving another axis can be programmed and start its travel while the other axis is still completing its task. This function alone reduces idle time by 40% to 50%.
Direct spindle indexing function

No need to wait for the spindle to decelerate then stop at zero point before indexing. Spindle indexing can now be achieved from a high speed rotation and stop directly at the desired degreed position instantly greatly reducing cycle time.

Rapid feed rate improvement

The Citizen K-series CINCOMs have a rapid feed rate of 32 meters per min. RPM Acceleration and Deceleration of the main spindle is 1½ times faster than that of a conventional lathe.

Fanuc FS31i processing

The control on the K-series provides faster mathematical processing thus reducing the interpolation period half as that of the conventional machine. Processing improvements on the control ladder is three times faster as that of our conventional lathes.

Longer machine operation

The tool layout concept allows the K-series machines to use the virtual X/Y axis movement similar to that of the B-series. This configuration has proven to be responsible for greatly reducing thermal growth displacement. Slides and heads now have higher rigidity enabling heavier cuts to be performed at longer periods of time.

The CINCOM K16 type VII can perform secondary machining operations with a standard X and Z axis on the back spindle thus allowing simultaneous machining capability. The K-series also has a centralized ball screw lubrication system and air seals on the back spindle.
