|Routered Wood Parts|
When wood blocks are routered or machined to a specific geometry, there are always rough surfaces and wood burrs or hairs where the router enters or leaves the part. The part pictured on the left shows this condition very clearly.
Removing these burrs and achieving a smooth finish is a relatively simple process. Barrel tumbling the parts with a Hardwood Media and White Aluminum Oxide Grit will clean up the part and leave it smooth and ready for further processing. The cycle time to accomplish this task will depend on how rough the raw part is, what grit size of abrasive is being used and how much edge rounding is desired.
Barrel tumbling is a better process than vibratory tumbling for this application. The barrel will force the entire load (media, abrasive and parts) to stay mixed and performing optimally. A vibratory process will likely tumble the media and parts but the abrasive will often not stay uniformly mixed.
