SYMPTOM
POSSIBLE CAUSES
SOLUTION
Uneven segment
wear
Segment cracks
(Wet cutting) Insufficient water (Usually
on one side of blade) Equipment defects
also can cause the segments to wear
unevenly.
Saw head is misaligned.
Blade is too hard for material being cut.
Flush water system. Check flow to both
sides of blade. Replace bad bearings,
worn arbor shaft or misalignment to
spindle.
Check alignment for squareness, both
vertically and horizontally, of the saw
blade.
3.6 Troubleshooting
Use a blade with a softer bond/matrix.
Segment loss
-Blade overheats because of lack of
coolant (water or air).
-Core is worn from undercutting.
-Defective collars/flanges set blade out
of alignment.
-Blade is too hard for material being cut.
-Blade is cutting out of round, causing a
pounding motion. Improper blade
tension.
-(Wet cutting) Check water lines. Make
sure flow is adequate on both sides of
blade and there are no blockages.
-Use sufficient water to flush out the cut.
-(Dry Cutting) Run blade free of cut perio-
dically to air cool.
-Clean collars/flanges or replace if they
are under recommended diameter.
-Use proper blade specification for ma-
terial being cut.
-Replace worn bearings; realign blade
shaft or replace worn blade mounting
arbor.
-When ordering blades, match shaft
speed of saw.
-Check spindle speed to ensure blade is
running at correct RPM. Avoid twisting
or turning blade in the cut.
