Deburring is the process of chamfering or rounding sharp corners formed on a metallic part during the machining process. Deburring can also remove the raised edges and small pieces of material that may remain attached to a workpiece after it has been machined by a cutting tool or grinding wheel. Finishing processes alter the surfaces of a workpiece to remove machining marks, scaling or pitting. Finishing can also enhance the appearance or function of the part and prepare it for subsequent coating processes such as bonding, plating or painting.
