What is the best way to cut 500 pieces as close to burr-free as possible or the easiest way to remove the burr? I can't visualize a punch and die to do the job but I wonder if there is a way. I cut them now on a band saw and use a fine belt sander. It's very time consuming and the parts get hot.

Drop saw with a carbide blade
Commercial aluminium window framers use drops saws here in Oz. No burrs, clean, quick cuts.
I cut aluminum on a table saw with a carbide blade. When the blade is fresh the burr is minimal, but as it wears I find I have to clean it with a belt sander also.
I would consider abrasive water jet cutting for that. I'm not sure how well laser cutting works for aluminum, but water jet should be fine.
Enjoy, DoN.
DoN, I had a well cover laser cut from 6mm aluminium chequer plate. Pretty much zero "kerf" or "burr". The finish was almost like it had been done with a bandsaw & then been "flame smoothed".
Cold saw.

We use drop saws in our factory. It makes a nice clean cut.
