The ongoing miniaturization and increasing precision of machine parts have made minute burrs generated in shearing, cutting, and grinding, a serious problem and their elimination a vital necessity. With no currently efficient way of deburring metal parts made by press-forming thin sheet metal. We applied a polishing using magnetic abrasives to micro-deburring, and used this in actual production. Results showed that three-dimensionally formed thin sheet hoops can be deburred, and clarified that nonstop operator-free deburring lines can be put into actual operation at production sites. We also attempted deburring the outer blade of an electric shaver as a practical application, attaining excellent results.
