Metal parts made by mass-production machining techniques almost always contain burrs, that is, irregularities in the form of sharp metal fragments attached to the machined surfaces of the part. Removing such burrs is an expensive yet necessary operation. The most common way by which this is done is for manual workers equipped with suitable small tools to inspect and clean up every part, an expensive and time-consuming process, especially when the burr is in an inaccessible position such as at the end of a blind hole machined in the part. There are some simple deburring operations which can be carried out by sand-blasting or tumbling methods, but the majority of situations are not amenable to any treatment other than careful hand-tooling.
