G0449/G0450 37" Drum Sander
A drum sander is used to remove surface material
from stock using a looping abrasive belt, which is
required when preparing a workpiece.
this entire
The primary components of the drum sander are
the sanding belt, sanding drum, conveyor belt,
conveyor drum, and pressure rollers.
A typical workpiece is sanded by turning the
sanding drum and conveyor motors ON. While
standing to the side of the sander, the operator
places the workpiece on the conveyor belt. As
the workpiece moves forward on the conveyor,
the front pressure rollers press down on the
top surface of the workpiece. The workpiece
moves forward, passing under the front and rear
sanding drums, which remove material from the
workpiece surface. A pressure roller behind each
sanding drum exerts downward pressure on the
workpiece, thereby minimizing the possibility of
the workpiece slipping and kicking back at the
operator. The operator receives the workpiece at
the rear of the sander.
Since the sanding drums only remove a small
amount of material, the workpiece is usually
passed through the sander, then turned 180° to
ensure an even cut. This is repeated to yield the
desired result.
The operator rotates the table height handwheel
to control the cutting depth. If the handwheel is
rotated
will be removed by the sanding drums.
Typically the operator installs a coarser grit sand-
paper on the front drum and a finer grit sandpaper
on the rear drum, then uses combinations of pro-
gressively higher grit numbers.
A variable speed knob allows the operator to
adjust the conveyor speed for the specific type of
workpiece and finish stage.
