Morphology
The phrase is fully compositional: 'axis' (a straight line used for rotation) modified by 'of rotation' simply specifies the axis concerned with spinning. This standard noun + of + noun pattern is cross-linguistically common and would be clear to a B1 learner who knows the constituent words.
Etymology
Axis of rotation pictures an invisible straight line that something turns around: the axis is the line and the rotation is the turning. That's why axis of rotation means the line an object spins around.
