Planing/Sanding - Grizzly G0677 Owner's Manual

Planing/Sanding

The Model G0677 is capable of planing and sand-
ing or sanding only. To achieve the best results,
experiment with conveyor feed rate, cutterhead
depth, sanding depth, various grits of sandpaper,
and oscillation speed. Also, for best results make
sure the workpiece has been surface planed on a
jointer before planing and sanding.
A typical planing and sanding pass will remove up
to ⁄ " of material. However, attempts to remove
1
8
too much material can cause jamming, wood
burning, rapid sandpaper wear or tearing, poor
finish, short motor life, and belt slippage. The
operator usually makes a pass, raises the table a
little, and repeats until the entire surface is both
planed and sanded.
Typically, no more than 0.5mm (approx. 0.020") of
material is removed during a sanding only pass.
The maximum sanding depth also depends upon
the thickness of the sanding belt, which can vary
from 0.010" (fine sandpaper) to 0.060" (coarse
sandpaper).
Planing and Sanding Workpieces
1. DISCONNECT THE
FROM THE POWER SOURCE!
2.
Open the upper left access door.
3. Make sure the cutterhead is set at the 0mm
position on the height scale. If not, loosen the
cutterhead lock handle, turn the cutterhead
adjustment shaft to the 0mm position on the
scale, then tighten the lock handle.
Note: We recommend setting the scale at
0mm for most planing/sanding operations.
4. Close and lock the left access door.
5. Make sure you have reviewed the Workpiece
Inspection on Page 33.
6. Put on safety glasses, a dust mask, and hear-
ing protection!
7. Make sure the machine is connected to
power and compressed air, and turn the dust
collector ON .

8.
Raise or lower the table until the workpiece is
approximately 1 ⁄ " (0.125") below the sanding
8
belt.
To do this: Measure the workpiece thick-
ness, then add ⁄ ", then fine tune with the
1
8
handwheel or the arrow keys.
9.
Push the SANDING BELT START button,
then push the FEED BELT START button.
10. Stand to the side of the feed belt to reduce
the risk of kickback, feed the workpiece into
the machine (see Figure 33), then raise the
table with the handwheel until the machine
begins planing and sanding the workpiece.
As the workpiece passes through the machine,
you should hear the cutterhead cut and the
sanding belt sand the workpiece.

correct body position and out of the way of
potential kickback.
11. Remove the workpiece from the outfeed side
of the machine.
12. Inspect the workpiece.
—If the workpiece is flat and smooth, shut the
planer/sander OFF.
