Thread: Buffer RPM questions

This is going to get complicated but here goes,,,

More important than rpm is surface speed,,,

A few people on here have done the math in threads Icedog/Brad did a great one...

What this means is that a smaller wheel going faster actually has a slower surface speed then a larger wheel going slower...

Grinders normally can't use the smaller wheels the walls get in the way, that is what I meant...And keep in mind there are different ones out there with different designs....

The best there is out there, is a variable 1100 -3500 Buffer but yes they are expensive...

A lower speed Buffer is next best at 1100 or 1725
or a variable speed Grinder motor like Brad has using bigger wheels this is another option...

I use the 3450,s but I use 4 inch wheels... Keep in mind I don't use the smaller wheels because of the speed, I use them because I can get into the Hollow grinds better...

The enemy here is heat if you can keep the heat down everything else is a moot point...
With a lower speed you can use more pressure than you can with a higher speed
of the SAME size... BUT is more pressure better??? or just faster??

For polish I use a 1725 I just haven't been able to get the right effect with a higher speed....

Another option is what Floppyshoes uses which is a variable speed Lathe with the buffer wheel attachment...

There are many paths to shine, and that was a ton of stuff I posted so go through it and think about it all..
But keep in mind it is all about heat and heat build up....
