Grinding Wheels are essential in metalworking but must be handled, stored and used with care to prevent damage and accidents. Here are key precautions to follow:

1. Proper Storage & Handling

• Store in a dry, temperature-controlled area, away from impacts.
• Inspect new and used wheels for cracks or damage before use.
• Carry wheels carefully-never drop or roll them. Use a hand truck or forklift for heavy wheels.

2. Safe Mounting

• Perform a ‘ring test’ to check for cracks before mounting.
• Ensure the wheel’s center hole fits snugly without forcing it.
• Use clean, flat flanges and tighten the spindle nut just enough to hold the wheel securely.
• Match directional wheels to the correct rotation.

3. Machine & Grinding Safety

• Make sure all guards and covers are in place before starting the machine.
• Let the wheel run at full speed for at least one minute before grinding.
• Never exceed the maximum RPM of the wheel.
• Grind gently-avoid excessive pressure that could cause overheating or brakeage.

4. The Ring Test

• Suspend or place the wheel vertically on a hand surface.
• Tap with a wooden handle 1-2 inches from the edge at a 45 degree angle.
• A clear ring indicates a good wheel; a dull sound may mean cracks.
• Always test before mounting, especially after storage.

Final Tip: Following these precautions ensures safe operation, prolongs wheel life and prevent accidents. Always prioritize safety when using grinding wheels.
