Keith, Why would your customer want to allow any degree of burr, pigtails or lifting on their edge connectors? The abrasive wheel that applies the chamfer to the cut edge should be rotating parallel to the connector contacts. As it cuts the chamfer, the copper is shaved down (in the direction of the cut edge), leaving no burrs, etc. to catch on the mating connector. If your customer will be mating these connector edges with a ZIF (zero insertion force) type locking connector, they may be able to tolerate some small amount.
