Metal stamping guides and resources for designers, engineers and metal part buyers. Valuable information for anyone considering metal stampings in their manufacturing process.
Secondary Process --- Deburring
Deburring is the process of removing sharp and rough edges from parts. Although burrs may be reduced in the tooling and design process there are certain conditions where they must be removed after forming.
Deburring can be accomplished in many ways depending on the size, material and shape of the part. Tumbling and agitating parts with an abrasive media is one way. Flat sanding with an abrasive belt is another.
When designing parts it is critical to call out on the drawing not only the exact requirements for eliminating burrs but also which surfaces this applies to. If a burr free status applies to only one side of a part this can be accommodated in the tool design process for the stamping thereby eliminating the need for a secondary process altogether - saving production time and cost.
Deburring processes may also be used for more than removing burrs. They may be used to polish and prepare surfaces to be coated or plated.
Better metal stampers will have complete deburring and surface finishing capabilities in-house. This assures a reduction in material movement time between operations as well as better quality control prior to other secondary operations including plating or painting.
