Deburring Methods for Machined Parts: Manual to Thermal
Why Deburr
Burrs scratch during assembly, hurt fits, act as fatigue sources and cut hands. On bearing fits they affect press and rotation.
Main Methods
- Manual: File, scraper, paper - flexible, low consistency
- Mechanical: Chamfer tools, brushes, vibratory finishing, blasting
- Chemical: Acid etch - complex cavities and small batches
- Electrochemical: Dissolution - precise and stress-free
- Thermal: Gas detonation burns burrs - cross-drilled parts
How to Choose
- Simple edge chamfer - chamfer tool
- Batch small parts - vibratory finishing
- Precise bores - electrochemical
- Complex castings - thermal
Quality Control
- Define chamfer or burr limits
- Sample with magnifier or vision system
- Clean after deburring
Huami Practice
Huami combines chamfering, vibratory finishing and cleaning; burr standards are in work instructions.
