Hello all,

My company has purchased a Mulitcam CNC router to use in making small aluminum dies. We use the dies for making rubber mats in a compression press. I have a problem with tooling marks left in the Aluminum (6061-T6) and I need to know how to get rid of them. We have used a dial indicator to ensure the router head is perpendicular to the machining plane. We have tried finishing passes, using ball nose bits with extremely high overlap (98%) and we still get marks which are visible in the rubber on the finished product. I am using consumables such as small steel brushes, sanding disks, ets now but this is tedious, and comes in a high cost in both the consumable and labor. Any help would be greatly appreciated.
