I’m sure there are big ticket high dollar machines that can do what your looking for.

My experience with widebelt sanders however is as many have mentioned above.

I use one daily for various tastes mostly sanding face frames and doors. Everything requires orbital and hand sanding after to break edges. Even going 80-120-150, platen or no platen. I’d be interested in the orbital type sander for doors mentioned above. That sounds like a dream!
