Not all burrs are created equal.  Some burrs are heavily rooted and some materials have a measure of plasticity.  These kinds of materials can pose a severe burr removal challenge for conventional mass finishing systems and require use of a high intensity and high energy finishing process such as centrifugal barrel finishing.   SEE    http://dryfinish.wordpress.com/2011/07/14/centrifugal-barrel-finishing-machinery/    Contrast the burr (edge) and surface condition of the top picture (finished) with that of the picture of the part prior to centrifugal finishing (bottom picture)

This view shows part condition after Centrifugal Isotropic Finishing. To see the original surface and burr conditions see the photo shown below. Note that not only have the heavily rooted burrs been removed but the surface machining marks have been blended in leaving a much more isotropic surface

Centrifugal Barrel Machine.  This type of equipment is capable of producing edge and surface finish results ten times faster than conventional barrel and vibratory finishing equipment.
