Blade Speeds (S.F.P.M.)

Blade teeth are designed for maximum cutting efficiency based on the recommended blade speed and feed pressure required for specific materials. Trying to cut material at speeds other than those recommended by the manufacturer will reduce the effective life of the blade.

Operating at the proper blade speed will achieve the correct shear angle for the tooth thus producing an ideal chip and more efficient cutting. If the blade speed is too high the tooth will run high in the cut removing too little material and producing thin chips. If the blade speed being used is slower than that recommended, the tooth digs too deep into the material causing stress on the tooth, possible tooth breakage, blade breakage or stalling in the work piece.

Feed Force

Feed force may be exerted in one of three ways. Gravity feed, which is the weight of the saw head; separate hydraulic feed rate and feed pressure controls; or a single servo control providing a combination ratio of feed rate and feed force applied to the blade.

Excessive feed force can allow small gullets to overload and choke causing crooked cuts and/or premature blade dulling. Excessive pressure can force larger or positive rake teeth too deeply into the material and cause tooth breakage or blade stalling.

Too little feed pressure will not force teeth deeply enough into the work thus increasing cut time and prematurely dulling blades

Blade Tensioning

Insufficient blade tension is a factor that is critical to the saws ability to make straight cuts. Also, excessive tension can stress the band and cause blade breakage. Turn the tensioning wheel until the blade is tight against the band wheels then give one more complete turn. Check the Tensioning Table on the 'Useful Information' page in the back of this book. Sawing creates heat which causes a blade to stretch. Check the blade tension periodically during operation.

Traverse Rate

Traverse rate refers to the speed at which the saw travels toward the work piece. Dropping the blade onto the work piece too quickly will cause severe damage including chipped teeth, stripped teeth, motor stalling or blade breakage. Once the blade has started a cut into the work piece you should then adjust the traverse travel to the correct feed rate for an ideal chip.
