Depth Of Cut; Bed Roller Height - Grizzly G0453 Owner's Manual

Depth of cut

the depth of cut on a planer means the amount
of material that is removed from the top of
the workpiece as it passes underneath the
cutterhead.
the depth of cut is set by adjusting the distance
of the table below the cutterhead. this distance
is the thickness of the workpiece minus the depth
of cut.
Although the correct depth of cut varies accord-
ing to wood hardness and workpiece width, we
recommend a maximum depth of cut no more
than ⁄ ". A series of light cuts will give better end

results and put less stress on the planer than try-
ing to take off too much material in a single pass.
the planing depth of cut is controlled by using
the table height handwheel on the right side of
the machine. rotating the handwheel clockwise
raises the table.
the depth of cut is read directly from the inch/mil-
limeter scale on the front of the planer, as shown
in figure 17.
one complete turn of the handwheel raises or
lowers the table approximately

Bed Roller height

Bed roller height range ..............0.002"–0.020"
the correct height of the bed rollers will vary,
depending on the type of material you intend to
plane. however, as a general rule, keep the bed
roller height within 0.002"–0.020" above the table
surface, as illustrated in figure 18.

above the table surface.
When planing rough stock, set the rollers high
to keep the lumber from dragging along the bed.
When planing milled lumber, set the rollers low to
help minimize snipe.
to ensure accurate results and make the adjust-
ment process quicker and easier, we recommend
using a rotacator (refer to Page 28) to gauge
the bed roller height from the table surface. if a
rotacator is not available, a straightedge and feel-
er gauges can be used, but care must be taken to
achieve accurate results.
