Hi, bit of a noob question here. I purchased a 200x300mm 10mm aluminium plate from my local metal supplier for the work surface on my PCB milling machine. They had to cut it from a large sheet with a saw. I expected this to be flat and the corners precise. Unfortunately, the plate was not anywhere near flat and the corners were terrible. Now I'm $70AUS out of pocket and I'm stuck with some useless aluminium.
Is it normal to have to get aluminium plate flattened? If so how is it usually done? Am I wasting my time and money? Should I look for another type of aluminium that is sold dead flat?
Massive frustration. So close to the finish line!! Please help me!
