摘要

The aim of this paper was to explore the correlation between the sanding efficiency and the surface quality, provided a standard for judging the end of belt life in the actual production, so that improved the overall economic efficiency under the premise of ensuring product quality. This study selected material type, Manchurian ash, Birch and medium density fiberboard (MDF), sanding direction (longitudinal and transverse) and granularity (60 and 100 grit) as influencing factors, analyzed their influence on the sanding efficiency and the surface quality, and observed the surface of specimens by SEM. Results indicated that the highest sanding efficiency was obtained by MDF when sanded with 60 grit abrasive belt, Manchurian ash acquired the lowest sanding efficiency when sanded with 100 grit abrasive belt in longitudinal direction. Moreover, the lowest Ra was yielded by Manchurian ash when sanded with 100 grit abrasive belt in transverse direction, MDF gained the highest Ra when sanded with 60 grit abrasive belt. It also could be noted that there was not a visible correlation between sanding efficiency and surface quality in all cases in this study, but the belt should be replaced when the material removal rate reduced to a certain level, so that acquire better product quality and economic efficiency.
