Wet diamond polishing drum wheel cylindrical how to use

A wet diamond polishing drum wheel is a cylindrical tool used for grinding and polishing hard materials such as granite, marble, and concrete.

Here's how to use it properly:

1. Ensure the Wheel is Suitable for Wet Use: The drum wheel should have holes drilled through it to allow water to keep the polishing surface wet. Using it dry can significantly reduce the life of the wheel .

 

2. Choose the Right Grit: Start with a coarser grit for heavy stock removal and progressively use finer grits to smooth and polish. For example, a 50-grit wheel is used for most of the work on concrete, while finer grits like 200 or 400 are used to remove scratches from the previous grit .

 

3. Secure the Wheel: Make sure the wheel is properly mounted on your grinder or polisher with the appropriate arbor size, typically 5/8".

 

4. Wet the Surface: Before starting, wet the surface to be polished to ensure adequate cooling and to reduce dust.

 

5. Use with Water: Always use the drum wheel with water. The water flow from your polisher should keep the wheel and the surface being polished wet .

 

6. Oscillate the Wheel: To wear the wheel evenly and avoid grooves, oscillate the wheel up and down during the polishing process .

 

7. Maintain a Constant Speed: Operate the grinder at a consistent speed recommended by the manufacturer, usually between 3000 to 3800 rotations per minute

 

8. Progressive Polishing: Start with the coarsest grit necessary for the job, and then move to finer grits as you progress. This will help to extend the life of the wheel and achieve a smoother finish.

 

9. Clean Up: After use, clean the wheel with water to remove any residue, and let it dry before storage.

 

Remember to always follow the manufacturer's instructions and safety guidelines when using a wet diamond polishing drum wheel. Wear appropriate safety gear, including eye protection, hearing protection, and a dust mask.
