What is Deburring?
Deburring is the process of removing burrs, sharp edges, excess material, and surface imperfections generated during manufacturing operations such as machining, drilling, milling, turning, laser cutting, stamping, casting, and molding.
Deburring helps:
- Improve part safety
- Enhance assembly performance
- Prevent component damage
- Improve product appearance
- Increase operational reliability
- Improve coating and finishing quality
- Extend component lifespan
Deburring is often one of the final steps before assembly, coating, or shipment.
