Blade Tensioning
Blade Tensioning
NOTICE
To prolong blade life, release the tension on the blade if the machine will be idle for an extended period of time.
Proper blade tension reduces the risk of blade breakage and improves cutting performance.
Note: The most accurate way to check blade ten- sion is to use the Model H5408 Blade Tensioning Gauge (see Accessories on Page 39).
To tension the blade, turn the blade tension handwheel until the blade tension gauge reads between 25,000 and 28,000 PSI.
Blade Care &
Break-In
Blade Care
A bandsaw blade is a delicate piece of steel that is subjected to tremendous strain. You can obtain longer use from a bandsaw blade if you give it fair treatment and always use the appropriate feed rate for your operation.
Be sure to select blades with the proper width, set, type, and pitch for each application. The wrong choice of blades will often produce unnecessary heat and will shorten the life of your blade.
A clean blade will perform much better than a dirty blade. Dirty or gummed up blades pass through the cutting material with much more resistance than clean blades. This extra resistance also causes unnecessary heat.
Blade Break-In
The sharp teeth tips and edges of a new blade are extremely sharp, and cutting at full feed rate may cause fracturing of the beveled edges of the teeth and premature blade wear.
To properly break-in a new Grizzly blade:
1.Choose the correct speed for the blade and material of the operation.
2.Reduce the feed pressure by half for the first
3.To avoid twisting the blade when cutting, adjust the feed pressure when the total width of the blade is in the cut.
4.Use the Chip Inspection Chart on Page 35 to check the blade efficiency.
