Slow Cutting Speed
|
|
Cause:
|
Usually occurs when a blade is used to cut a material that is too hard for the
segment. The hard material wears the exposed diamonds, but not the metal portion of the segment. The segment
wears too slowly, no new diamonds are exposed and you see slow cutting speeds.
|
|
Solution:
|
Cut a soft, abrasive material until diamonds are well exposed. Try asphalt, block, sandstone, or dried mortar. Choose the proper blade for the application.
|
| Potential:
|
If this problem is allowed to continue, heat builds up and the blade
begins to bounce leading to segment loss, core cracks and a very unsafe condition
|
| |
|
Short Blade Life
|
| Cause:
|
Usually occurs when a blade is used to cut a material that is too soft and abrasive for the
segment. The abrasive material wears the metal of the segment too fast, and you see short blade life.
|
| Solution:
|
Specify the correct blade for your application. Check water flow. Make sure the blade is rated for the
equipment used. Check saw is in good condition.
|
| Potential:
|
If blade specification is not changed, the problem will reoccur. Customer will not get the full blade
life and efficiency of the diamond tool
|
| |
|
Core or Segment Cracks
|
| Cause:
|
Blade is too hard for the material. Saw is in need of repair. Blade is mounted
improperly. Overheating. Twisting while cutting or attempting to cut curves.
|
| Solution:
|
Specify a softer bonded blade for the material. Check all bearings, belt, shaft, and flanges.
Check direction of blade travel. Follow guidelines for proper blade operation and cooling procedures.
|
| Potential:
|
If this problem is allowed to continue, it will result in segment loss and possible core
destruction. This is an extremely dangerous situation. Do no continue to use this blade.
|
| |
|
Wobbling/Warped Blade
|
| Cause:
|
Blade is out of tension...the steel core is not straight. Wrong size collars or
mounted incorrectly. Blade is allowed to overheat (bluish-black marks). Blade run at improper RPM.
|
| Solution:
|
Return blade to factory for repair. Use the correct size blade collars. Check flanges are smooth
and tight fitting. Follow guidelines for proper blade operation and cooling procedures. Check RPM rating for blade
and saw.
|
| Potential:
|
If the problem is allowed to continue, heat builds up and the blade begins to bounce leading to
segment loss, core cracks and a very unsafe condition. Produces poor quality cuts.
|
| |
|
Undercutting:
|
| Cause:
|
Steel core is worn faster than segments by abrasive material being cut.
|
|
Solution:
|
Specify a blade with a wear-retardant design. Increase water flow to flush cut.
|
| Potential:
|
If this problem is allowed to continue, the core will wear out from under the segment and allow the
segments to separate.
