Synchronous spindle pair
Synchronous operation involves a following spindle (FS) and a leading spindle (LS), referred
to as the synchronous spindle pair. The following spindle imitates the movements of the
leading spindle when a coupling is active (synchronous operation) in accordance with the
defined functional interrelationship.
