Function
Use the thread cutting cycle to produce cylindrical and tapered external and internal threads
with constant lead in longitudinal and face machining. The thread can be single or multiple.
With multiple threads, the individual thread turns are machined one after the other.
The infeed is performed automatically; you can choose between the variants constant infeed
per cut or constant cutting cross-section.
Right-hand or left hand thread is determined by the direction of rotation of the spindle which
must be programmed prior to the cycle start.
Both feed and spindle override are ineffective in the traversing blocks with thread.
