It can take 10 to 20 minutes for the CNC to engrave one box. What takes the longest are deep/wide areas like the 'N' in Nimbus or the IE logo, because it can't engrave that depth in one pass - it has to go back and forth over the same line, each time stepping down slightly. These widest parts cut nearly all the way through the thickness of the enclosure, so the IE takes longer than all the control labels combined.
Another interesting thing is that it's possible to engrave after paint, so that negative space is painted and the text is silvery (clear-coated aluminum) - inverted from the usual effect.
That must look bad ass! So much cooler then just paint!
So... Wanna do IE mags for my car
I feel like when I was working on the nursery when my daughter was about to be born. LOL.
