Polishing Technology and Phenomena of The Inner/Outer Surfaces of Small Cup-Type Nickel Tube -Study of Ultraviolet-Ray Aided Machining-
Our main purposes were to establish ultraviolet-ray aided machining (here after reffered to as U-RAM) and clarify the chemical and mechanical polishing mechanism.The inner/outer surfaces of small cup-type nickel tube is strongly required to polish,simultaneously.The present study deals with the new development of simultaneous polishing technology and the verify of polishing phenomena that uses a photocatalyst and a cathilon (a luminous dye:Cathilon Brilliant Flavine;hereafter referred to as cathilon) excited by an ultraviolet ray (hereafter referred to as UV).Measurements and observations clarified that TiO2 of 0.18-μm grain size polished chemically/mechanically the outer surface using cathilon,and cathilon chemically polished the inner surface of small cup-type nickel tube,simultaneously.Further measurements indicated that the chemical erosion roughened the inner surface,when cathilon increased from 2.5,5 to 20wt%.An increase of TiO2 to 20wt% at 20wt% of cathilon did not result the flatter surface.Aluminum oxide does not provide the polishing ability due to the poor photocatalyst effect compared with TiO2.
