Deburring and deflashing services serve to round sharp edges or corners and remove flash or parting lines from forging, casting or molding operations. Deburring and deflashing services are provided by contract finishers, surface finishing shops and facilities with specialized deburring processes. Deburring and finishing are typically one of the last steps in the manufacturing process and are often the most critical. Deburring removes burrs or other surface defects (deburrs), smooths parting lines in castings, deflashes molded parts, rounds off sharp edges and radiuses or chamfers corners. The deburring or edge finishing facility may have a variety of processes or tools for burr or flash removal such as: 1.) Abrasive flow machining (AFM) 2.) Electrolytic or electrochemical deburring 3.) Etching or chemical deburring 4.) Fixed abrasives finishing or surface conditioning (abrasive belts, discs or nonwoven wheels) 5.) Hydrodeburring or high pressure water blasting 6.) Mass Finishing 7.) Rotary cutting tool processes (rotary burs, files or chamfering tools) 8.) Sandblasting or abrasive blasting 9.) Thermal deburring processes or thermal energy machining (TEM) 10.) Wire or abrasive brush deburring Some deburring shops will specialize in a few advanced finishing processes, while other finishers or finishing processors will provide a broad array of edge conditioning techniques. Depending on the specific process and component to be deburred, the deburring contractor may finish parts in manual, off-hand, fixtured, automatic or robotic modes. Controlled or selective deburring processes allowing finishing of a select region or portion of part. Industrial applications for deburring includes finishing of molds & dies, automotive and combustion engine parts (injectors, manifolds, etc.), medical devices, spray and nozzle orifices, high cleanliness or purity pharmaceutical or semiconductor flow components (tube fittings, elbows, tees and reducers, valve bodies or housings, regulator or flow controllers, etc.) and aerospace or jet engine blades, disks, hubs and shafts. Deflashing, fettling or smoothing of parting lines or flashing on castings, forgings, and molded parts is another application. Removal of burrs, generation of accurate radius geometry and achieving a smooth surface condition helps eliminate potential stress concentrators and can improve fatigue strength of the component. Fatigue strength is particularly important in applications where components are exposed to a high number of load cycles such shafts or parts in jet engines, pumps or other types of rotating machinery.
