Safe Buffer RPMs for Polishing Aluminum
A discussion started in 2009 but continuing through 2019July 14, 2009
Q. I would like to know many RPMs a buffer can go before it burns the aluminum. I'm looking to get a good/fast buffer and want to make sure I get one that will do the job quickly without damaging the aluminum.Allan Shapiro

A. It depends on the diameter of the buffing wheel. 6000 surface per minute is about the maximum, or roughly 2000 rpm for a 12" diameter wheel.

A. The diameter of your buffing wheel will determine the surface speed of the buff. In my experience I prefer a shaft speed of about
1600 rpm. The faster turning machines make your work a little more tricky (dangerous) and the polishing compounds fly off the faster turning buffs.

Q. What max rpm for buffing aluminum with a 2" dia pad and a 3" dia pad? These size pads and light weight buffers are great for tight places on aircraft without wearing your shoulders out. Thanks.Gabe fernandez
