Diamond Wheel Won’t Cut

Troubleshooting Guide – Diamond Wheels

Issue Potential Source of Problem Suggested Fix
Wheel not cutting / Wheel burning / Excessive heat / Excessive noise Wheel is loaded or glazed RPM/SFM too high Bond too hard Use Eagle suggested method to dress your wheel and open the bond
Reduce RPM/SFM
Use a freer cutting bond specification
Rapid / Excessive wheel wear
Poor shape retention
Excess heat due to improper coolant nozzle orientation
Overfeeding
RPM/SFM too low
Bond is too soft
Add coolant or Improve coolant nozzle positioning and pressure
Reduce feed rate and/or depth of cut
Increase RPM/SFM
Use a harder, better form-holding bond
Poor Finish Grit size is too coarse
Grinding wheel is out of balance/has run-out
Wheel is loaded or glazed
Bond is too soft
Use a finer grit
Check all spindle bearings and/or belts
Check to ensure wheel is balanced and true
Use Eagle suggested method to dress your wheel and open the bond
Use a harder bond

FAQ

Q:  Can I use a Diamond wheel on steel?
A:  It is not recommended to use Diamond wheels on steel, or any ferrous material.  Diamond wheels are used primarily on Carbide, Ceramics, Glass.  We recommend using CBN wheels for any ferrous material such as Steels.

Q:  Is a C75 wheel softer than a C100 wheel?
A:  This can be true, but there are many other considerations to be made when determining bond hardness.  Discuss your project with one of our Application Engineers for the best bond recommendation.  Ask about our Bond Development Program

Q:  Will a D120 grit cut more aggressively than a D150 grit?
A:  This can be true, but there are many other considerations to be made when determining bond hardness.  Discuss your project with one of our Application Engineers for the best bond recommendation.  Ask about our Bond Development Program

Q:  Is there a “one size fits all” type bond that will work on many applications?
A:  Depending on the application, there will normally be a sacrifice made if trying to use one wheel for multiple applications.  The wheel may not cut as aggressively, or may leave a poor finish.  Discuss your projects with one of our Application Engineers for the best bond recommendation.  Ask about our Bond Development Program

Q:  Can Resin Bond wheels be re-coated?
A:  The cores of Resin Bond wheels are easier to balance and true when made new with each wheel
