Morphology

hone + machine

The noun phrase is directly compositional: 'honing' is the verbal noun from 'hone' (to sharpen or finish a surface) and 'machine' denotes a device, so together they denote a machine that performs honing. This follows a common noun+noun/verb‑noun compound pattern that a B1 learner who knows both constituents can readily interpret.

Etymology

Honing machine is a tool that gently rubs a part with a rough stone or sand to make its surface 'smooth' and its shape 'precise'. The word honing shows the rubbing action and machine tells you it is done by a device, so the phrase means a machine that improves a part's finish and shape.
