|
Arbor Out of Round
|

|
Excessive Wear Undercutting
|
Using the wrong blade specification on highly abrasive materials.
|
Change to a more resistant abrasive bond.
|
|
Lack of sufficient coolant to the blade, often detected by excessive wear in the center of the segment.
|
Ensure the water supply system is functioning properly.
|
Wearing out of round accelerates wear, usually caused by bad bearings or loose/wrong “V” belts.
|
|
Replace bad bearings or worn “V” belts.
|
||
|
Core Cracks
|
Blade is too hard for the material being cut.
|
Change to a softer bond.
|
|
Excessive cutting pressure, or jamming or twisting of the blade.
|
The saw operator should use steady, even pressure without twisting the blade in the cut.
|
Overheating due to inadequate water supply or not allowing a dry blade to cool intermittently.
|
|
Use adequate water on wet cutting blades and ensure proper airflow for dry blades.

Uneven Side Wear
|
Insufficient water, generally on one side of the blade.
|
Ensure water is being distributed evenly on both sides of the blade.
|
|
Equipment problem, causing the blade to wear out of round.
