SEGMENT CRACKS
UNEVEN SEGMENT WEAR
t
t
t
(In wet cutting) Insufficient water
(usually on one side of blade).
Equipment defects also can cause
the segments to wear unevenly.
Saw head is misaligned
REMEDY
t Flush water system.
t Check flow to both sides of blade.
t Replace bad bearings, worn arbor
shaft or misalignment to spindle.
t Check alignment for squareness both
vertically and horizontally, of the saw
blade.
CAUSEPROBLEM
t Blade is too hard for material being cut. t Use a blade with a softer bond/matrix.
SEGMENT LOSS t Blade overheats because of lack of
coolant (water or air).
t Core is worn from undercutting.
t Defective collars/flanges set blade out
of alignment.
t Blade is too hard for material being cut.
t Blade is cutting out of round causing a
pounding motion.
t Improper blade tension.
t (Wet Cutting) Check water lines.
t Make sure flow is adequate on both
sides of blade and there are
blockages.
t Use sufficient water to flush out the
cut.
t Clean collars/flanges or replace if they
are under recommended diameter.
t Use proper blade specification for
material being cut.
t Replace worn bearings; realign blade
shaft or replace worn blade mounting
arbor. When ordering blades match
shaft speed of saw.
t Check spindle speed to ensure blade
is running at correct RPM
t Avoid twisting or turning blade in the
cut.
CRACKS IN CORE t Blade flutters in cut as a result of losing
blade tension.
t Blade specification is too hard for the
material being cut.
t Tighten the blade shaft nut.
t Make sure blade is running at proper
speed and that drive pin is functioning
properly.
t Use a softer bond/matrix to eliminate
stress
