Deburring is the first stage of metal surface treatments.
This procedure is performed by using suitable abrasives that eliminate any imperfections resulting from fusion operations. Components and mechanical parts generally require this kind of operation before they are ready for their final use, as fusion does not allow for accurate dimensional tolerance.
Actually, in most engineering applications, components must be interchangeable in order to function reliably during their expected life. It is therefore necessary to achieve a dimensional tolerance that primary technological processes are unable to achieve.
Moreover, metal surfaces often present distortions and alterations, that require finishing operations such as grinding to obtain the final dimensions and the required surface quality.
