What is the correct procedure when dressing a grinding wheel?

• A. Dress the wheel to restore the abrasive and remove glaze
• B. Increase the wheel speed to improve cutting
• C. Use a dull wheel for smoother cuts
• D. Remove the guard during dressing

Answer: (A)

Dressing a grinding wheel reconditions the wheel by removing glaze and exposing fresh abrasive grains, which restores the wheel’s cutting action and helps it run true. When a wheel gets glazed or loaded with work material, it stops cutting efficiently and can overheat the workpiece. Dressing reestablishes the wheel’s texture and geometry, so you get cleaner cuts, better control, and less heat buildup. To do it correctly, keep the machine running at operating speed and the guard in place. Use a proper dressing tool and apply light, even pressure as you move the dresser across the wheel’s face, keeping the dresser at a small angle to true and re-shape the surface. After dressing, inspect the wheel for a uniform surface and ensure everything is safe to continue. Increasing the wheel speed is unsafe and doesn’t fix the cutting action. A dull wheel will cut poorly and overheat the work, and removing the guard during dressing is a serious safety violation.
