Development of Mirror~like Polishing System for Hemispherical High-¬speed Precision Bearing for Digital VTR Drum
디지탈 VTR 드럼용 반구 고속 정밀베어링의 경면연마 시스템
Abstract
Mirror-like polishing system of hemisphericall high-speed precision bearing for digital VTR drum was developed. Mechamism of the polishing process was analyzed in the view point of polishing contact range and contact length between the tool and the workpiece surface. It was suggested that the two stage polishing process adoptiong the diamond grinding wheel and polishing tool instead of multistage lapping processes, which enables the mass production of the bearing by reduction of polishing time.
