Changing Feed Rate
As a general rule, slower feed rates are more
beneficial than faster feed rates since they allow
a given belt to remove more material. We recom-
mend you always start with the slowest feed rate
and only increase the feed speed as needed to
meet your sanding goals. Be sure to always test
the feed rate using scrap wood similar to your
workpiece.
Softwoods typically require a faster feed rate than
hardwoods; however, there is no definitive rule to
follow when determining the best feed rate to use
for any type of wood.
Also, keep in mind that an increase in feed rate
will increase the amperage load for a given sand-
ing depth. This means you need to use shallower
sanding depths at higher feed rates to avoid over-
loading the sanding motor.

The conveyor belt has three feed rates, which
are controlled by the chain position on the
sprockets of the feed motor and conveyor roller
(see
Figure 37).
