Diamond Blades Troubleshooting
Why the blade wears abnormal?
  • Usually caused by dirty water, insufficient water supply to blade, low powered drive motor, worn bearings or shaft, incorrect blade for material being cut.

 

Why the blade wears the segments unevenly?
  • Check bearings and spindle for wear, machine alignment and equal water supply to both sides of blade.

 

Why the Blade wobbles?
  • 1,Incorrect mounting of blade / remount blade correctly.
  • 2,Worn bearings or bent shaft / replace worn bearing or blade shaft.
  • 3,Blade RPM too high or incorrect tension / ensure blade is running at correct RPM.

 

Why the blade cut slow?
  • 1,Blade becoming glazed due to use on material too hard for bond / To sharpen blade, make fast (3- 4m/min) shallow (3-10mm deep) passed in the material being cut, or in sandstone or asphalt for quicker results.
  • 2,Excessive cutting pressure, high shaft RPM, low machine HP or drive belts loose / tune engine according to manufacturer's manual.

 

Why undercut the steel center?
  • Abrasion of steel center due to highly abrasive material being cut / use sufficient water to flush out the chipping or choose blade with protective teeth

 

Why the steel center cracks?
  • 1,Excessive cutting pressures / slow down the cutting speed and keep correct feed rate.
  • 2,Incorrect blade tension / ensure blade is running at correct RPM.
  • 3,Jamming or twisting in cut / keep sawing straight when the blade working (concave blade exceptional)
  • 4,Overheating / check water feed system and make sure the water flow is adequate on both sides of blades.
  • 5, Blade too hard for material being cut / use proper blade specification for material being cut.

  • 2,Overheating due to lack of water / check water feed system and make sure the water flow is adequate on both sides of blades.
  • 3,Blade twisting or jamming in cut / keep sawing straight when the blade working (concave blade exceptional)
  • 4,Out of round blade / replace worn bearing, realign blade shaft or replace worn blade arbor.
  • 5, Incorrect blade tension / ensure blade is running at correct RPM.
  • 6,Excessive cutting speed / slow down the cutting speed .
