The
first stage in the utilisation of any wood, involves machining.
In these processes, the geometry of cutting tools, the speed
of their cutting, the rate of feed and the manner of feed
of the material play a prominent role in deciding the quality
of the machined material and consumption of energy for the
required operations. A suitable combination of these properties,
determined quantitatively under standard conditions, is known
as the working quality. The economy, efficiency, and safety
factors are governed by the machining properties and the working
quality of the wood in question. Rubberwood has been subject
to most types of machine operation and qualitative experience
is available on its working. Nevertheless, few quantitative
data are available on the machining properties.
Wood finishing is the effect of various surface finishes,
painting, polishing etc, on wood. In the case of rubberwood,
qualitative experience indicates that it can be worked to
a good finish suitable for high class furniture. The finish
adaptability is rated at 94% of that of teak under standard
conditions. Rubber wood can be easily worked on a lathe,
but is not that good for boring and mortising. Ammonia treated
rubberwood, free from blue stains, has exhibited better
finish adaptability and water gloss than untreated or blue
stained rubberwood.
