Abstract
The abrasive sanding process is the most labor-intensive operation in the Rubberwood furniture manufacturing industry. Although the machining properties of Rubberwood (Hevea brasiliensis) are well established, information on its abrasive sanding characteristics is sparse. This study was carried out to establish the optimal abrasive sanding regime for Rubberwood. The results suggest that the abrasive sanding process can be optimized when well machine-planed Rubberwood stocks are used. Further, it was found that when the machine surface quality was good, abrasive sanding with a two-level sequence of grit sizes was sufficient to produce an acceptable surface smoothness. The improved surface smoothness also minimized the coating film spread on the wood surface. This finding will serve as a useful benchmark for machine-planing and abrasive sanding processes in the high-volume Rubberwood furniture manufacturing industry.
Zusammenfassung
Das Schleifen ist der aufwändigste Arbeitsvorgang bei der Herstellung von Möbeln aus Gummibaumholz (Hevea Brasiliensis). Obgleich seine Be- und Verarbeitungseigenschaften im Großen und Ganzen erfasst sind, sind die Informationen hinsichtlich der Schleifeigenschaften noch spärlich. Die vorliegende Untersuchung wurde durchgeführt, um den Schleifvorgang von Gummibaumholz zu optimieren. Die Ergebnisse weisen darauf hin, dass der Schleifvorgang durch Verwendung von maschinell gut vorgehobeltem Gummibaumholz optimiert werden kann. So zeigte sich, dass für eine gut gehobelte Oberflächenqualität ein zweifacher Schleifvorgang mit unterschiedlicher Korngröße ausreichte, um eine akzeptable Oberflächenglätte zu erzielen. Die so verbesserte Oberflächenqualität ermöglicht darüber hinaus die Minimierung der benötigten Beschichtung. Diese Erkenntnis setzt einen wertvollen Maßstab für das Hobel- und Schleifverfahren für die wirtschaftlich bedeutende Möbelherstellung aus Gummibaumholz.
