Definition
Meaning
To remove rough edges or ridges from a piece of material, especially metal or plastic, after a cutting or machining process.
To smooth or finish a workpiece; more broadly, to refine or perfect a rough or unfinished output.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation. Russian might use "удалять заусенцы" (remove burrs) or "снимать фаску" (chamfer), which are descriptive phrases, not a single verb.
Common Mistakes
- Confusing with 'debug'. Using as an intransitive verb (e.g., 'The part deburrs well').

FAQ
Frequently Asked Questions
No. Deburring specifically removes sharp protrusions (burrs) created by cutting. Polishing is a broader process of making a surface smooth and shiny, often done after deburring.
A burr is a rough edge or ridge left on material (metal, plastic, wood) after a cutting, drilling, or stamping operation.
Yes. While most common with metal, it is also correctly used for plastic, acrylic, and sometimes even wood or printed 3D parts.
The process is 'deburring'. The result is a 'deburred' part. The rough edge itself is a 'burr'.
