Cause: The material slips during cutting which twists or james the segments loose.
Remedy: Hold the material securely while cutting.
Cause: Blade is too hard for the material it is cutting, causing excessive dullness which causes the segment to pound off.
Remedy: Use a softer blade specification.
Cause: Worn blade flanges fail to provide proper support and cause the blade to deflect.
Remedy: Replace worn arbor and/or bearings.
Cause: Overheating. Usually easily detected by bluish color on steel center, generally confined to the area where the segment was lost.
Remedy: Check the water system for blocked water passages. Test pump to see if it is functioning. For dry cutting, it may be necessary to make shallower cuts and allow the blade to run freely every few minutes in order to let the air cool it.
Repair note:
It is possible to replace two or three diamond segments, providing the steel center is not cracked or undercut badly. If many segments are missing, or if there is less than 50% of blade life remaining, repairing the diamond blade may not be economical.Be certain to eliminate mechanical or operational problems before installing replacement blades.
