Thread: size of the bufing wheels

The bigger the wheel, the faster it is going.

I hopes this helps you see it better.

Correction...a 6" wheel travels 6" x 3.146 (Pi) = 18" +
a 8" wheel travels 8" x 3.146 ( Pi ) = 24" +
assuming both are rotating the same speed.

A 3600 RPM buffer travels at 60 revolutions per second irregardless of the buffing wheel size.

So...... the distance covered per second....

18" x 60 = 1080 " per second
24 " x 60 = 1440" per second

More distance = greater heat
