Trouble shooting diamond saw blade

In our daily use of diamond saw blades, there are some bad situations, especially when novices use them. CDT has summarized the following troubleshooting methods for diamond saw blades based on more than 20 years of experience for your reference.

 

1 Diamond Segment(Causes/Remedies)

* Blade too hard for material being cut / use proper blade specification for material being cut.

* Overheating due to lack of water / check water feed system and make sure the water flow is adequate on both side of blades.

* Blade twisting or jamming in cut / keep sawing straight when the blade working(concave blade exceptional).

* Out of round blade / replace worn bearing,realign blade shaft or replace worn blade arbor.

* Incorrect blade tension / ensure blade is running at correct RPM.

* Excessive cutting speed / slow down the cutting speed.

* Undercutting of steel center / use sufficient water to flush out the cut or choose blade with protective teeth.

 

 

2,Blade worn out of round(Causes / Remedies)

* Incorrect mounting of blade / remount blade correctly.

* Worn bearings,Spindle or blade arbor / replace worn bearing, realign blade shaft or replacce worn blade arbor.

* Blade too hard for material being cut / use proper blade specification for material being cut.

* Blade arbor out of round(Caruses / Remedies).

* Blade incorrectly seated /  remount the blade correctly.

* Worn flanges or flanges not properly tightened / tighten flanges properly or replace worn flanges.

* Blade shaft worn / replace worn blade shaft.

 

3. Diamond Segment cracks(Causes / Remedies)

* Blade too hard for material being cut / use proper blade specification for material being cut.

 

4. Steel center cracks(Causes / Remedies)

* Excessive cutting pressures / Slow down the cutting speed and keep correct feed rate.

* Incorrect blade tension / ensure blade is running at conrrect RPM.

* Jamming or twisting in cut / keep sawing straight when the blade working(concave blde exceptional).

* Overheating / check water feeding system and make sure the water flow is adequate on both sides of blades.

* Blade too hard for material being cut / user proper blade specification for material being cut.

 

5. Undercutting the steel center(Causes / Remedies)

* Abrasion of sttel center due to highly abraisve material being cut / use sufficient water to flush out the cipping or choose blade with protective teeth.

 

6. Slow cutting (Causes / Remedires)

* 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 material being cut or in sandstone or asphalt for quicker results.

* Excessive cutting presure, high shaft RPM, low machine HP or drive belts loose / tune engine according to manufacturer's manual

 

7. Blade wobbles(Causes / Remedies)

* Incorrect mounting of blade / remount blade correctly.

* Worn bearings or bent shaft / replace worn bearing or blade shaft.

* Blade RPM too high or incorrect tension / ensure blade is running at correct RPM.

* Uneven segment wear.

* Check bearings and spindle for machine alignment and equal water supply to both sides of blades.

* Abnormal wear.

* Usually caused by dirty water, insufficient water supply to blade, low powered drive motor, worn bearing or shaft, incorrect blade for material being cut.
