Introduction: Deburring and Polishing
Abrasive wheels ease an edge by removing small amounts of material.
Safety for Abrasive Wheels
- Never wear gloves.
- Always wear a full face shield.
- Pieces must be held with both hands.
- Pieces under 4 inches must be held with locking pliers, like VISE-GRIPS.
- Only work in the safe portion of the wheel.
- Hold material so that it is angled down.
- Do not push material horizontally into the wheel.
Deburring and Wire Wheel
DEBURRING WHEEL (LEFT)
The deburring wheel is a soft wheel made for easing an edge; it is not for removing lots of material like a grinding wheel does. For heavy stock removal, use the disc/belt sander.
A sharp edge will destroy the deburring wheel; be aware of the contact angle between the material and wheel.
WIRE WHEEL (RIGHT)
The wire wheel is for smoothing a rough surface, like rust or welding slag.
The buffing wheels are for putting a high polish on plastic.
- The wheel on the right is coarse, and will remove more material; use this first.
- The wheel on the left is finer and will polish to a higher sheen.
Before polishing plastic, press the compound block against the rotating wheel to load it with a compound.
- Do not apply compound directly to the workpiece.
Note: Using the polishing wheel is messy. Coveralls and a hat are recommended.
- Roll up your sleeves.
