What is deburring, edge finishing & surface conditioning?
www.sme.org/desc One dictionary defines a burr as “a thin ridge or area of roughness produced in cutting or shaping metal.” For most people, this definition conveys the basic idea of a burr. However, for engineers charged with removing burrs from manufactured parts, a process known as “deburring,” this definition is inadequate. What constitutes a “burr-free” part varies among companies and quality control departments. For some, it means having no loose material at an edge. For others, it means having nothing visible to the naked eye or an edge condition that will not cause any functional problem in the next assembly process. Missing material or a hump of rounded metal at an edge may or may not be called a burr. Burrs and sharp edges create many problems. Sharp edges can be the result of inadvertently leaving a sharp edge or can come from producing a burr that typically has many sharp facets. Burrs on sheet metal parts, for example, cause premature tearing during forming. Plating over b
