What does "deburring" mean in metalworking?

Deburring refers specifically to the process of removing sharp edges or burrs that can form on the edges of cut metal. When metal is cut, whether through shearing, grinding, or other means, the cutting process can leave behind rough, sharp edges known as burrs. These burrs can be hazardous, leading to injuries during handling or further processing. By deburring, workers ensure that the metal edges are smooth and safe for assembly, installation, or further machining. This not only enhances the safety of the manufacturing process but also improves the overall quality and finish of the final product.

The other processes mentioned do not align with the definition of deburring: polishing deals with enhancing surface finish rather than edge safety, casting involves shaping metal in molds, and bending refers to changing the shape of metal without cutting. Thus, the primary focus of deburring is on edge safety and finishing.
