Deburring

Definition - What does Deburring mean?

Deburring is a material modification process that removes sharp edges, or burrs, from a material, and leaves the material with smooth edges. Deburring is commonly performed after machining operations, which typically leave sharp edges on the material. Deburring can be performed using a wide variety of methods.

Corrosionpedia explains Deburring

There are many methods available for deburring. One of the most popular is mechanical deburring. Mechanical deburring can be performed manually or with a machine, and includes rubbing the part with sandpaper, using a manual deburring tool with a sharp edge specifically designed to remove burrs, or abrading the burr away with a metal file. Common types of mechanical equipment for deburring include belt sanders, grinding discs, countersink drill bits, grit blasting and tumbling machines.

Another popular method to remove sharp edges from a material is electrochemical deburring, in which the material being deburred is immersed in an electrolytic solution. Once immersed, an electrical current is sent through the part. The current density is naturally highest at the thin, sharp burrs, and the metal ions of the burrs are transferred from the component into the electrolytic solution, removing the burr. Electrochemical deburring is popular because it can remove many burrs quickly and leave the remainder of the part unaffected.
