How to Make Apple’s Mac Pro Holes
On the subject of Apple's hole-machining process, I recently noticed how tiny the light-grill holes are on the older wireless Apple keyboards: <a href="https://i.imgur.com/l9n9Cp2.jpg" rel="nofollow">https://i.imgur.com/l9n9Cp2.jpg</a>. Look at the ruler, marked in mm - the holes are less than .1mm in diameter. I was wondering how they did this, I guess a laser or plasma cutter is the only way?
