Automatic Swiss-Type Lathe

The K16 CNC features a tool layout that uses the virtual X/Y axis movement to yield reduced thermal growth displacement, says Marubeni Citizen-Cincom, Inc.


Two independent tool posts can move at the same time and in the same direction to reduce non-cutting idle time. For example, the machine does not need to wait for a tool post to return to a waiting position for the other tool post to start the next process.


In any thread cutting operation, one axis can be programmed to start its travel while the other axis is still completing its task. According to the company, this overlapping axis function alone reduces idle time by 40 percent to 50 percent. In addition, spindle indexing can now be achieved from a high speed rotation and stop at the desired degreed position, thus reducing cycle time. With this direct spindle indexing function, there is no need to wait for the spindle to decelerate then stop at zero point before indexing.
