CRACKS IN STEEL CENTER
1. Blade flutters in cut as a result of blade losing tension.
Tighten the blade shaft nut. Make sure blade is running at proper tensioned
speed and that drive pin is functioning properly.
2. Blade specification is too hard for the material being cut.
Use a softer blade bond to eliminate stresses that create cracks.
3. Bad blade shaft bearing.
Replace blade shaft bearing.
4. Overheating due to lack of water.
Check water feed lines and make sure flow is adequate on both sides of
blade.
SEGMENT CRACKS
1. Blade is too hard for material being cut.
Use a blade with a softer bond.
2. Blade being “forced” through the cut causing chattering.
Run Saw at normal speed. “Open” blade by sharpening in abrasive material.
