Griots 6" Polisher - Correct Machine Speed

Hi,



I just got my Griots Random Orbital 6" polisher.



I watched the DVD and noticed that the pad spins about 1 or 2 revolutions per second. When I use mine, it spins like a washer on spin cycle. Is this right? how fast should it be going?



BTW - I did adjust the speed setting, it does go slower on 1, but not much.



Thanks!

I dunno how much stock you should put in this response as I haven't even taken *my* Griot's 6" out of the box yet :o But..



Don't confuse the two motions that the machine does- circular rotation and elliptical orbiting. (If you already have a firm grasp of this, I hope you don't consider me too pedantic or condescending).



The rotation of the pad is not powered, it's free-wheeling. It's the other motion, the elliptical orbiting, that's powered.



So how fast it orbits depends on the speed setting.



How fast, or how much, it *rotates* is dependent on how much friction there is between the pad and the surface being polished. Besides what pad and product you're using (and how much of that product), that friction is primarily a matter of how much pressure you're applying.



I'd pick the correct (orbit) speed for the job (which'll be the highest two speeds when you're doing normal polishing) and as long as the pad is rotating, I wouldn't worry much about it. *Generally* I'd say that you want fairly slow rotation.

i believe the dvd is old and the 6" random orbital in the video, is not the newer one sold now...

Thanks for the reply... I would be interested in finding out if yours reacts the same way.



I figured spin rate would reduce if I applied pressure. appears that the pad rotates on its own and the motor just spings the entire assembly..



One would think they could actually grab a hold of the disk and try to slow or stop the rotation... mine just spins like a drill..



Now, if its suppose to react that way, then thats fine, I'll just start using it.



Thanks again!
