Zusammenfassung:	PURPOSE:To prevent seizure and lap and to improve the yield of a copper wire having high surface quality by pickling a roughly drawn wire and polishing mechanically the wire so as to leave grooves on the circumferential surface then drawing the wire thereby improving the deposition of lubricating oil in the stage of drawing. CONSTITUTION:A roughly drawn wire is processed by mechanical polishing to leave 10-40mu grooves at
