Blade Tips & Troubleshooting - Segment Loss

Cause:
Material slips during cutting which twists or jams segments loose.

Remedy
Hold material securely while cutting.

Cause
Blade is too hard for material it is cutting, causing excessive dullness which causes the segment to pound off, or fatigue.

Remedy
Use a softer blade specification.

Cause
Worn blade flanges fail to provide proper support and cause blade to deflect.

Remedy
Replace both blade flanges.

Cause
Out-of-round blade rotation resuling in pounding, caused by worn arbor or bad bearings in the shaft.

Remedy
Replace worn arbor and/or bearings.

Cause
Overheaing. Usually easily deteced 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 missing diamond segments, providing the steel center is not cracked or undercut badly. If many segments are misssing, or if there is less than 50% of blade life remaining, repairing the diamond blade may not be econoomical. Be certain to eliminate mechanical or operational problems before installing replacement blade.
