Stainless steel pipe with fine hole and long size has recently been needed for the flow line of pure gas and liquid, which is used in the field of precision machinery. Inner wall polishing of the capillary is very difficult by ordinary finishing methods. High speed slurry flow finishing method developed by authors has been proved to have excellent polishing performance, but it has been needed a long time to obtain an acceptable level of surface roughness decrease. In the present study, effect of an annex of the glass beads into the slurry on the efficiency of finishing has been investigated. Experiments show that the medium of the glass beads annexed into the slurry has fine finishing characteristics rather than slurry medium. Surface roughness decreases with slurry flow pass number and its decreasing modes vary due to the property of medium. Optical micrographs of the medium indicate that the glass bead does not crush and not slenderize during finishing processes.
