Best way to slit brushed aluminum composite board (to eliminate ridges)

[Tropics09]

One of our big name customers is requesting 18x24 building signs out of brushed aluminum composite. Ive noticed that our slitter leaves a ridge on each side where it cuts. Any advice on how to decrease/eliminate this?
FYI- We have a Fletcher Substrate Cutter.
Also keep in mind that a new substrate cutter is not an option, and we do know that we can have the brushed aluminum composite pre-cut from our distributor, but we would like to maximize profits.

Your input and advice is greatly appreciated.

Cheers!

We use a 1/2" steel bar- slide it along the cut edge and it curls the bur under and give a nice finished edge. Gene

sand the edge afterwards, or use a straight edge and a hand router. Cut on a table saw. The foolproof method would have someone with a CNC router cut them for you.
