Sharpening
!
WARNING!
The bandsaw blade is sharp
and can cause cuts. Warning
for personal injury. Wear
protective gloves whenever
you handle the bandsaw blade.
After sharpening, the bandsaw blade should be
set as described in the instructions on the
previous page.
The more accurate the sharpening, the straighter
and smoother the bandsaw blade runs when
cutting the log.
Radii
The radius in the area (A) should be 1-3 mm.
A radius under 1 mm increases the risk of
cracking.
A radius over 3 mm means that the chips are not
broken.
Angles
The clearance angle should be 10-12° and the
cutting angle (F) varies depending on the spe-
cies of wood as follows:
Hardwoods or frozen timber
Medium hardwoods
Softwoods
Before sharpening, the bandsaw blade's teeth
should be set using the saw setting pliers.
The rake angle should be 90°. See the figure to
the right.
Shape of the Tooth
As the bandsaw blade is sharpened it is
important that the teeth and tooth valleys keep
their original shape.
For optimal results, the bandsaw blade should
be sharpened with the grinder. The procedure is
described on the following pages.
On delivery, the grinder is adjusted for the
correct angles and tooth shape.
