If you watch the iPhone 5 trailer you actually see the process of how they chamfer the edge using a robotic grinding wheel. My guess is the loose metal shards are not falling cleanly off the body of the phone or they are getting bashed around during the rest of the production process.
Hard to say without seeing every stage of the process tbh.
