4.7 Thread synchronizing
If you wish to re-machine a thread, it may be necessary to synchronize the spindle to the
existing thread turn. This is necessary as by reclamping the blank, an angular offset can
occur in the thread.
Constraint
Thread synchronizing is not possible if a toolcarrier is used (B axis).
Note
Activating/deactivating thread synchronization
If a thread synchronization is active, then this is active for all of the following "Thread turning"
machining steps.
Thread synchronization remains effective without deactivation even after the machining has
been shutdown.
Requirement
The spindle is stationary.
One threading tool is active.
