-28- G0504 16" Horizontal Resaw Bandsaw
Blade Information
Blade choices are limited due to the specialized
nature of the Model G0504. The only variables
when selecting a blade are the type of cutting
tooth and the number of teeth-per-inch (Tooth
Pitch).
Blade Tooth Type
Carbon Steel—The least expensive type, car-
bon steel blades are adequate for most cutting
applications; however, they dull quickly and for
economical reasons they are usually replaced
rather than resharpened.
Carbide-Tipped—The most expensive type, car-
bide-tipped blades are designed for continuous
use in production shops. They hold a sharp
edge longer than carbon steel and they can be
resharpened many times before needing to be
replaced.
Tooth Pitch (TPI)
Tooth pitch refers to the number of teeth-per-
inch. The more teeth-per-inch, the smoother the
resulting cut, but the feed rate must be relatively
slow. The less teeth-per-inch, the rougher the
resulting cut, but the feed rate can be set faster.
Some trial and error may be necessary to find
the right combination of cut quality, tooth pitch
and feed rate.
Blade Care
The resaw blade is a delicate piece of steel that
is subjected to tremendous strain. You can obtain
longer use from the blade if you give it fair treat-
ment and always use the appropriate feed rate
for your operation.
A clean blade will perform much better than a
dirty blade. A dirty blade passes through the
cutting material with much more resistance than
a clean blade. This extra resistance will also
cause unnecessary heat. Maintain your blades
with a cutting blade lubricant like SLIPIT
® (Model
G5562/3 in the Grizzly Catalog).
Blade Length
The required blade length for the Model G0504
is 180".
Blade Width
The required blade width for the Model G0504
is 1".
Blade Breakage
Blade breakage is unavoidable, in some cases,
since it is the natural result of the peculiar stress-
es placed on the blade. Blade breakage is also
due to avoidable circumstances, which is most
often the result of poor care or judgement on the
part of the operator when mounting or adjusting
the blade or support guides.
The most common causes of blade breakage
are:
•
Not releasing blade tension after use.
• Faulty alignment or adjustment of the
guides.
• Using a blade with a lumpy or improperly
finished braze or weld.
• Feeding the workpiece too fast.
• Tooth dullness or absence of sufficient set.
• Excessive or too little blade tension.
• Running the bandsaw excessively when not
resawing.
