Basic Functions of a Bandsaw
A properly adjusted bandsaw can be safer to
operate than most other saws and performs
many types of cuts with ease and accuracy. It is
capable of performing the following types of cuts:
Straight Cuts
• Miters
• Angles
• Compound Angles
• Resawing
• Ripping
• Crosscutting
Irregular Cuts
• Simple and Complex Curves
• Duplicate Parts
• Circles
• Beveled Curves
Basic Cutting Tips
Here are some basic tips to follow when
operating the bandsaw:
• Replace, sharpen, and clean blades often for
best performance. Check guides, tension, and
alignment settings periodically and adjust
when necessary to keep the saw running in
top condition.
• Use light and even pressure while cutting.
Light feeding pressure makes it easier to cut
straight, reduces blade lead, and prevents
undue friction or strain on the bandsaw
components and the blade.
• Avoid twisting the blade when cutting
around tight corners. Allow the blade to saw
its way around the corners. Always use relief
cuts when possible.
• Misusing the saw or using incorrect
techniques (e.g. twisting the blade with the
workpiece, incorrect feed rate, etc.) is unsafe
and results in poor cuts.
Workpiece Inspection
Some workpieces are not safe to cut or may
require modification before they are safe to cut.
Before cutting, inspect all workpieces for the
following:
• Material Type: This machine is intended
for cutting natural and man-made wood
products, laminate covered wood products,
and some plastics. Cutting drywall or
cementious backer board creates extremely
fine dust and may reduce the life of the
bearings. This machine is NOT designed
to cut metal, glass, stone, tile, etc.; cutting
these materials with a bandsaw may lead to
injury.
•
Foreign Objects:
Nails, staples, dirt, rocks
and other foreign objects are often embedded
in wood. While cutting, these objects can
become dislodged and hit the operator, cause
kickback, or break the blade, which might
then fly apart. Always visually inspect your
workpiece for these items. If they can't be
removed, DO NOT cut the workpiece.
• Large/Loose Knots: Loose knots can become
dislodged during the cutting operation.
Large knots can cause kickback and machine
damage. Choose workpieces that do not have
large/loose knots or plan ahead to avoid
cutting through them.
• Wet or "Green" Stock:
Cutting wood
with a moisture content over 20% causes
unnecessary wear on the blades, increases
the risk of kickback, and yields poor results.
• Excessive Warping: Workpieces with
excessive cupping, bowing, or twisting are
often dangerous to cut because they can
be unstable and unpredictable when being
cut. DO NOT use workpieces with these
characteristics!
•
Minor Warping:
Workpieces with slight
cupping can be safely supported if the
cupped side is facing the table or the fence.
On the contrary, a workpiece supported on
the bowed side will rock during a cut and
could cause kickback or severe injury.
