During machining, no matter how advanced and sophisticated the equipment is, parts will have burrs. Burrs are extra metal bits that form on the edge of machined materials. They happen when something squishes the material, especially if it is flexible or tough.
Burrs not only affect the appearance of the parts but also reduce the function and safety of the parts. Deburring is important in machining because metal parts undergo various steps like cutting, stamping, and milling during manufacturing. These processes shape machined parts, but leave small metal burrs on the surface. Drilling, engraving, turning, and other machining processes can also leave burrs on the metal surface.
