Abrasive Wheels Machinery Safety Checklist

Always follow manufacturer's instructions and recommendations for safe and proper use.


  • Are all flanges maintained in good condition?
  • When the bearing surfaces become worn, warped, sprung, or damaged, are they trued or refaced?

Mounting inspection

  • Immediately before mounting, are wheels closely inspected and sounded by the user (ring test) to make sure they have not been damaged in transit, storage, or otherwise?
  • Immediately before mounting, is the spindle speed of the machine checked to be certain that it does not exceed the maximum operating speed marked on the wheel?
  • If the wheels sound cracked, are they not used?
  • Are the wheels dry and free from sawdust when applying the ring test, (otherwise the sound will be deadened)?
