I use the term rotary for any machine that has forced rotation only... For the machines that have an orbit but let the pad float free I use the term random orbital... For machines that have both forced rotation... ...I use the term dual action.
That's how I use the language and I'm not trying to be the speech police here, but I think there needs to be a clear distinction between the three different actions.
Calling a random orbital a dual action as if it is the same thing isn't accurate and creates a lot of confusion.

I LOVE THIS TOPIC! Thanks Bob for bringing it up. Good to see you posting. I like an old pro's point of view.
That being said... I've listed my comment of disagreement and explanation below.

What i don't like is when any RO or DA is just referred to as a pc. A pc is a porter cable, as in the name brand. But I agree completely with the OP, calling the polisher by the right term would help save many from confusion.
Yeah, I really don't like it either.

Porter Cable machines were the first ones that obtained volume used due to the concerns with the first Infiniti Q45's and their flourinated clears, in the late 80's. Mequiars was the leader on finding the use for the Porter Cable and broadened it's visability to the industry. As a result, the term "pc" become part of the detailer lanquage, much as Kleenex, being the first highly advertised and marketed facial tissue, is the "term" still used by many when they request a facial tissue. Other mass market products have attained similar status, however, no matter how much time/money and such are spent, it sometimes just doesn't happen.

True. I recall reading about your introduction to the machine awhile back.
If I recall correctly, you were with a couple Meguiar's guys at the docks in Long Beach working on getting some cars squared away upon their arrival into the USA. Correct me if I'm wrong.
Back to WhyteWizard's point of the thread:
I
disagree that the designation is not accurate. I count the random rotation as an action DEFINITELY, making the random orbital a true dual-action machine (orbital and random rotation created by centripetal force). Just because it's not belt, gear, or directly driven doesn't discount the motion. In fact, I think that if the random orbital did not exist in its current form (and nobody thought of building it using the common design), someone would be
trying to figure out or
would have figured out
how to offer up random rotation, using some sort of mechanical slip-action device. It's simply too capable and desirable a feature.
In my eyes, claiming it's not a dual-action machine is akin to discounting the drive capability of a transmission that uses a torque converter (or fluid coupler) , versus one that uses a clutch and pressure plate.
I don't doubt that the original intent or use of the term dual-action was likely used in conjunction with a machine that featured a gear or direct drive of some sort. But, as time goes by, specific terms become slang, or used as a loose definition rather than a specific name of a machine. Just try and ask for the
air-powered palm-style random orbital in a body shop! Everyone's in too big a hurry (or it's too loud to hear all those words), so the term
DA identifies the machine just mentioned. If you want the BIG GUN, you ask for a "mud hog" (heavy duty, large stroke, Bondo® eating random orbital or forced rotation orbital).
I like to use the terms:
• Rotary
• Orbital
• Random Orbital
• Forced Rotation Orbital
• Dual Mode
Looking through recent manufacturers literature, it seems most are avoiding using the designation dual-action altogether, except interestingly, Meguiar's! Their G110v2 random orbital machine is actually named
Professional Dual-Action Polisher. As Ron Ketcham mentioned, Meguiar's introduced it to the masses for use as a paint polishing tool. Even though I personally may have used the term
DA in my writings perhaps 3 or 4 times over the past few years, I make every effort to use the proper term
random orbital.
Here's some of the latest literature and images I could find online, and with exception of Meguiar's, the term
dual action is not being used:
Meguiar's G110v2 is named the
Professional Dual Action Polisher:
Flex uses the term
Orbital Polisher to describe its XC 3401 VRG:
Rupes uses the term
Planetary Sander to describe its EK 150AE:
Makita calls it's BO6040 (a favorite of the WhyteWizard) a
Random Orbit Sander with switchable
Forced Rotation:
Bosch says the 1250 DEVS features switchable
Turbo driven eccentric orbit mode:
