Setting Cut Depth
Adjusting the
SUPERMAX
for the proper contact between the abrasive and the stock determines the mechanical
depth of cut.
Determining the depth of cut is the most important set-up procedure
before operating the
SUPERMAX Sander
. It may take some experimentation to determine the proper depth of cut, given the variables of
abrasive grit, type of wood, and feed rate. For best results, use scrap wood to practice sanding and to develop skill
and familiarity with the machine before doing finish work.
When sanding with grits finer or less than 80 grit, best course of action is to raise the Conveyor Table so the
Drum(s) contacts the workpiece but still can be rotated by hand.
When using grits coarser or greater than 80 grit, one can raise the conveyor table slightly more.
A combination of several variables will determine the proper depth of cut to use, including the following:
1.) Abrasive Type and Grit Size.
2.) Width of the piece.
3.) Hardness of the Piece.
4.) Feed Rate of the Conveyor Belt.
The depth of cut of the secondary drum is controlled by the 2-two adjustment knobs
(Analog Indicators)
located
on both sides of the drum.
The Drum Adjustment Knobs
allow proper depth of cut with virtually any abrasive grit
combinations on the drums. The two drums are normally both used during sanding operations, but either the
primary or secondary drum can be used alone.
Primary Drum-
To adjust the Primary Drum, set the drum height equal to the thickness of the piece to be
processed.
This is most easily done as follows:
1.) Lower the conveyor table to a depth greater than the thickness of the board. Do not start the drum currently.
2.) Start the conveyor and feed the board until it is beneath the drum(s).
3.) Raise the conveyor table so the drum(s) contact the board, but the drum(s) can still be rotated by hand.
4.) Continue to run the board through the machine. This is the setting for the first sanding pass.
The depth of cut can be measured on the depth gauge, or by fractions of a revolution of the height adjustment
handle. (
Note:
One revolution of the handle will raise the table 3/32 of an inch; 1/3 of a turn will equal 1/32 of an
inch, etc.).
Secondary Drum-
On dual drum models, sanding with a different abrasive grit on each drum is possible in a single
pass. The coarser abrasive is wrapped on the Primary (Front) Drum for dimensioning and surfacing of the wood,
while the finer abrasive is wrapped on the Secondary (Rear) Drum. When used in this way, the Secondary Drum is
positioned just slightly lower than the Primary Drum, so it removes the scratches left by the coarser grit on the
primary drum
(Figure 14)
.
However, the exact depth of cut of the secondary drum will depend on the specific abrasive grits on each of the
