i get confused with above statement.
higher speeds( we assume speed is same and just wheel changes)+bigger wheels= less heat?
this is what i was thinking.
let me explain why i think so.
arbor speed is 3600 x 6. will make buffer turning more faster then 8 wheel?
am i wrong?
8 wheel has more surface and touching speed to the razor should be less then 6 wheel because 6 will radius smaller and will touch more then 8 wheel/
Am i clear on this?
An easier way to look at this is that for any given RPM, just consider a single revolution of the wheel. A six in wheel travels 6 inches. An eight inch wheel travels 8 inches in the same amount of time, so the larger wheel went farther so it's going faster.

The bigger the wheel, the faster it is going.

I hopes this helps you see it better.
