Blade Information

The Model G0503 is a specialized machine that requires specialized blades. Grizzly Industrial has selected a series of blades for optimum per- formance on this machine. 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 less expensive carbon steel blades are adequate for most cutting applica- tions; however, they dull quickly and for economi- cal reasons they are usually replaced rather than resharpened.

Carbide Tipped—The more expensive carbide- tipped blades are designed for continuous use in production shop situations. They hold an edge longer than carbon steel and they can be resharpened many times before needing to be replaced.

Tooth Pitch

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 Length

The required blade length for the Model G0503 is 168".

Blade Width

The required blade width for the Model G0503 is 1".

Blade Care

The resaw blade is a precision ground piece of steel, subject to tremendous strain. Increase the life and performance of your blade by using the correct feed rate and tension.

A clean blade will perform much better than a dirty blade. A dirty blade passes through the cut- ting material with much more resistance than a clean blade. This extra resistance will also cause unnecessary heat. Maintain your blades with a cleaner like OxiSolv® and a cutting blade lubri- cant like Boeshield® T-9 shown on page 32.

A cool blade will last longer than a blade that is overheated. The best way to keep the blade cool is with a coolant dispenser like the Grizzly model H4959 shown on page 33.

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 may also be due to avoidable circumstances, which is most often the result of poor care or judge- ment on the part of the operator when mounting the blade, tensioning, or adjusting the support guides.

The most common causes of blade breakage are:

•Incorrect blade tension.

•Feeding the workpiece too fast.

•Dull teeth or insufficient set.

•Not releasing blade tension after use.

•Faulty adjustment of the blade guides.

•Using a blade with an improperly finished braze or weld.

•Running the bandsaw excessively when not resawing.
