TROUBLESHOOTING
DIAMOND BLADE DOES NOT CUT
Cause
The segments are too hard for the material
Solution
Check if the blade is suitable for the material
Cause
The segments have become blunt
Solution
Sharpen the segments by cutting an abrasive material (e.g. sandstone)
Cause
Insufficient machine power
Solution
Check the voltage, machine power & filters
EXCESSIVE WEAR
Cause
The segment is too soft for the material (e.g. if a blade for hard material is used
to cut abrasive material)
Solution
Check if the diamond blade is suitable for the material
CRACKING OF STEEL CENTRE
Cause
The segments are too hard for the material
Solution
Check if the blade is suitable for the material
Cause
Excessive cutting pressure, overheating, material slippage, twisting or jamming in the cut
Solution
Leave the blade to do the work, do not exert too much pressure & allow the blade to cool
regularly by leaving it to rotate away from the workpiece for a few seconds
LOOSENING OR CRACKING OF SEGMENTS
Cause
The segments are too hard for the material. This results in the diamond blade bouncing
in the cut resulting in cracking segments
Solution
Check if the diamond blade is suitable for the material
SCORCHING OF SEGMENTS
Cause
Excessive cutting pressure causing overheating. This is easily recognisable from the blue
colouring where the segments & the steel core are welded together
Solution
Allow the diamond blade to cool regularly by rotating the blade away from the workpiece
for a few seconds
Cause
The segments are too hard for the material
Solution
Check if the diamond blade is suitable for the material. Alternatively use less cutting
pressure & let the blade do the work
UNDERCUTTING
Cause
Undercutting occurs when the steel core wears faster than the segment, i.e. where the
segment & steel core meet. This is usually caused by materials that are highly abrasive.
The cutting debris is not removed sufficiently & the steel core is affected. Undercutting is
certain to occur if a diamond blade for hard materials is used to cut abrasive materials
Solution
Use a diamond blade suitable for the specific material
