Hi everyone i’m actually new in machining ! I have a question if you can help me , I actually have some steel and aluminum blocs and I want to improve their surface to make it plan and to have the same thickness everywhere. The first idea I had is a drum sander or a wood planer , it might work with aluminum but definitely not with steel. I know that milling with fly cutter on a CN machine will work for me but it takes a lot of time and cost expensive ! I’m looking for machine that can do the job for aluminum and steel bloc
