CNC work on Steel Panels

The only way to drill a steel panel is to use our CNC machine but it is very inconvenient for less than at least 20 panels


So if I wanted to order large amount of cases (20+) with the intent of building and selling my own amps, I could work it out to get a steel chassis like the Galaxy but have the rear panels custom CNC machined for necessary holes?

For thin gauge steel, you would be utilizing a CNC punch press, and then have the panels bent, if required. You could also use water-jet for the panel shape and holes.

Any particular reason why you want steel, and not aluminum?
