Morphology
The meaning 'rotation of an object around its own axis' is directly and transparently derived from combining 'axial' (related to an axis) with 'rotation' (spinning around an axis). Although somewhat technical, the compound follows standard compositional noun phrase formation and has clear cross-linguistic equivalents, so a B1 learner who knows the constituents should grasp the MWE.
Etymology
Axial rotation gives a clear image: axial refers to an axis, the straight line through an object's center, and rotation means turning. So the phrase means 'turning around its own axis'.
