lowered on four jackscrews turned simultaneously by a slip-free chain
drive. That chain drive also
keeps the table level at all
heights. The chain drive has
an automatic tensioning
system built in to reduce
setup and adjustment. The
table height system is
operated by a large cast iron
handwheel at the top of the
POWERMATIC Dual
Drum Sanders. An easy-to-
read depth gauge next to the
table makes presetting table
for specific material
thicknesses easy.
The conveyor is driven by a two-speed gearbox (left) that is shifted while the belt is
running. Each side of the conveyor has an easy adjuster (right) for belt tracking and
tension
The heavy-duty poly conveyor belt provides a positive grip on the material being sanded. The
high-quality conveyor belt has tracking adjusters at either end of the table. These adjusters also
control belt tension.
The 1/4HP feed motor drives the conveyor belt and is
controlled by a two-speed forward/reverse gearbox that
produces feed rates of 8 and 12 SFPM (surface feet per
minute). The gearbox can only be shifted between the low
and high feed rates while the machine is running. The
conveyor belt can also be reversed, using a separate three-
position switch with forward, off and reverse positions.
Reversing can be handy in the event that a problem
develops, the belt can be reversed to safely bring the piece
back out. That lets you correct the problem more easily.
Industrial-tough controls, including a full
magnetic switch protect the
POWERMATIC Dual Drum Sanders.
The POWERMATIC Dual Drum Sanders are designed with
the industrial environment in mind. They are tough, easy to
use and easy to maintain. Their wide capacity ranges mean
one machine handles more jobs, making the P
Dual Drum Sanders a very cost-effective investment.
