Most of the manufacturing & fabrication processes produce undesired Burr.As industry is striving for high speed, highly productive and efficient machines, the components going in these machines need to be highly precise. Residual burr in such assemblies may result in malfunctioning of machine which in-turn would result in loss in productivity and efficiency. Deburring process ensures removal of even minute secondary burr from the component which results in smooth & extended product life. Deburring has over the years become a Critical Operation for Many components.
Deburring a part satisfactorily and consistently requires a large experience of various deburring methods and tools. The amount of burr created by every metal cutting process is different in nature, and varies with the material, hardness, and sharpness of the cutting tools/dies.
Put simply, finishing and deburring machines are designed to remove imperfections that remain attached to workpieces after they’ve been modified by another machine. These undesirable raised edges are commonly known as burrs, and they fall into one of two categories:
Mechanical burrs result from operations like shearing, stamping, or folding.
Thermal burrs, often called slag or dross, are caused by heat-generating machines like laser cutters.
There are a variety of factors that can lead to the formation of burrs including the type and thickness of the metal being worked, condition of the die, blade clearance, and pressure or power exerted by the machine.
Understanding the Differences between Deburring and Finishing
Deburring involves removing any raised edges or small pieces of material that remain attached to a workpiece after it’s been modified.
Finishing is done to alter the surface of a workpiece, getting rid of any scaling and pitting to enhance its quality or prepare it for a next step like painting.
Other common operations done with finishing machines can include calibration and stock removal (a machining operation done to achieve higher material removal rates and decrease variations), slag grinding (targeting slag produced by thermal cutting machines), and edge rounding (any action that breaks the edge of a metal part, but especially those that form an edge radius).
