What is Deburring and Why is it Important? Deburring is the process of removing small imperfections, called burrs , that form along the edges or surfaces of a part during manufacturing. These burrs may be tiny, but they can: Cause safety hazards (sharp edges can injure operators) Interfere with assembly and part fit Reduce product lifespan by creating wear points Diminish visual appeal Lead to functional failures in precision systems In industries where accuracy, safety, and quality are non-negotiable, deburring is an essential finishing step. How Do Burrs Form? Burrs are usually the result of mechanical operations such as: Milling and drilling Turning and sawing Stamping and punching Laser cutting Casting and molding They come in several forms: Poisson burrs – material displacement from stretching Roll-over burrs – pushed material over the edge Break-out burrs – fractures from tool exit What are the Main Deburring Methods? 1.
