If you program the "Complete" program step, you must enter "Pull
blank: Yes" and "Parting cycle: Yes" in the "Pulling" step. Then you
can program the "Parting" function. The workpiece is then cut off after
it has been gripped or pulled out of the main spindle.
You do not need to specify the amount by which the workpiece is
pulled out of the main spindle in this case as this is calculated from the
parting cycle parameters.
The two program blocks "Complete" and "Parting" are linked in the
machining plan.
As soon as machining on the rear face of a workpiece is finished,
machining on the front of the next workpiece starts. You can activate a
work offset in the meantime for machining the front face using the
"Front face" function. You will typically use the work offset that was
active before the workpiece was gripped.
The main spindle is now the master spindle again.
Manually rotate the counterspindle chuck to the desired position,
and move the tool to the desired position.
Press the "Various" and "Counterspindle" soft keys.
