Buffing Wheels
• Keep buffing wheels raked out before each
use and when buildup gets heavy during use
Raking means to clean buffing wheels with
a wheel rake to remove built-up compounds
and metal particles ALWAYS use light
pressure when raking wheels!
• Do not mix two different compounds on same
wheel For best results, use a separate wheel
for each compound
• Always use an upward stroke with heavy
to moderate pressure for cutting Use a
downward stroke with light pressure for
polishing (see Figure 12)
• Wear safety equipment when buffing If
polisher forces workpiece out of your hand,
be prepared for it to come flying at you!
Wear safety glasses or a face shield and
a heavy leather apron Also, wear a dust
mask to protect your lungs from microscopic
particulate that will be flying off wheel
Use caution when polishing plated metals;
there is a chance that thinly-plated materials
could be damaged. Light pressure is all that is
needed for quality work.
Buffing wheels are available for most types of
metals, some woods, and for different stages
in the buffing process Below are pictures and
descriptions of common wheel types
Only use buffing wheels with a wheel speed
rating higher than RPM of buffer.
