introduction: The main problem with polishing is excessive polishing。The so-called excessive polishing means that the longer the polishing time, the worse the surface condition。Excessive surface polishing usually refers to the following two phenomena:“Orange peel peel”with“pinhole” 。It should be noted that the chances are usually greater when machine polishing is used。 1 Orange peel peel: After polishing,The surface of the workpiece has an irregular peeling layer of orange peel,The main reason is that the material is soft、Due to excessive polishing pressure,The hard material can withstand high polishing pressure,Not prone to excessive polishing。 Increases when the polished surface deteriorates
