Morphology
The meaning is directly compositional: a 'polishing machine' is simply a machine used for polishing, which a B1 learner who knows 'polishing' (the process of making a surface smooth/shiny) and 'machine' (a powered device) can readily infer. This follows a common noun + noun compound pattern found across languages, so the sense is transparent and predictable from its parts.
Etymology
Polishing machine is a name for a machine that does polishing. One clear image is a motor turning a rough wheel or pad that rubs a floor or metal until it becomes smooth and shiny. So, the term means 'a machine that makes surfaces smooth and shiny'.
