Why does my Jet Grinder have burning spots and cracks?

  Pamela MartinezJul 31, 2025
  Burning spots and cracks can occur on your workpiece due to several reasons. It may be caused by improper operation, so you should reduce the feed amount and use proper crossfeed speed. Another cause may be improper heat treatment, in which case you should perform the heat treatment again. Finally, it could be due to an unsuitable grinding wheel, so dress the wheel finely and frequently and consider using a softer and rougher wheel.

  If you notice minor scratches on the surface of your workpiece, it could be due to improper operation. To resolve this, dress the wheel, ensure the wheel edge is parallel with the workpiece, slow down your crossfeed, and make sure the workpiece is securely fastened to the table. Another cause could be improper dressing of the wheel. Try tightening the dresser, using the proper dressing speed, and avoiding dressing too deep at one time.

  Maureen MooreAug 12, 2025
  If you're experiencing frequent waves on the surface of your workpiece, it could be due to excess machine vibration. Ensure the machine is level and on a solid surface, and check the spindle. Another potential cause is an unbalanced grinding wheel; in this case, dress and balance the wheel. Finally, the wheel might be too hard, so try using a softer or rougher wheel and reduce the feed amount.

  Kevin ChaseAug 17, 2025
  If the wheel on your Jet Grinder dulls and grit falls off, it's likely because the wheel is too soft. To address this, reduce the table and crossfeed speed. If possible, increase the wheel diameter and lightly dress the wheel repeatedly.

  Tina CowanAug 25, 2025
  Poor grinding ability, wheel clogging, and burns on the workpiece can occur if the wheel is too hard. To resolve this, increase table and crossfeed speeds, reduce the wheel diameter or width, use a sharp diamond for dressing, and use a rougher wheel.
