Petropedia explains Deburr
Burrs are commonly formed errors on machining operations such as grinding, drilling, milling, engraving or turning. They may be present in the form of fine wires on the edges of a freshly sharpened tool or as raised portions of a surface. These types of burrs are commonly formed when a hammer strikes a surface. These raised portions and sharp edges need to be removed for efficient processes, safety of individuals working on the machines as well as avoiding any operational failures in the long run. Deburring accounts for a significant portion of manufacturing costs.
There are several methods that can be used to remove burrs. Abrasive substances may be applied, or abrasive cloths may be used to rub the metal in order to remove thin shavings and small notches, as well as to polish the piece. In other cases, sanding may be necessary, whether this means a small amount of sanding by hand or rigorous sanding with a machine for more troublesome deformities. Other methods require repetitive filing or use of a grinder to smooth away nicks and fragments. Deburring and polishing may be necessary for more than one section of a metal component, since burrs and shavings can occur on seams as well as edges.
