Key principles.
Hand tool
File or scraper. Most common for low volume.
Mass finish
Tumble parts in media. Production batch deburring.
Heat-driven
Heat removes burrs. For internal complex geometry.
Selective
ECM deburring removes burrs from specific areas.
Surface treatment
Bead blast simultaneously deburrs and finishes surface.
During machining
Deburring designed into machining program. Tools chamfer edges.
FAQ
Sharp burrs injure handling, interfere with assembly, harbor contamination.
Manual for prototypes, low volume. Vibratory for production runs.
In-line cheaper per part. Separate operation enables better quality.
Per drawing or industry. Aerospace specifies maximum burr per critical feature.
Manual $10-30/part labor. Vibratory $1-5/part at volume. ECM specialty.
Specify edge break (chamfer or radius) on drawing. Or note "deburr per ASTM xxxxx".
