Mechanical Brush Deburring
Mechanical brush deburring is a finishing step where sharp burrs and edges are removed with rotating wire brushes. This prevents injuries and improves flow characteristics and edge strength.
Physical-Chemical Mechanism of Action
Mechanical brush deburring uses the friction between the brush and the surface to remove sharp burrs and edges. The rotating brushes remove microscopic cracks and irregular structures, improving the surface finish and making it smoother.
Metallurgical Relevance & Risks in Welding
A smooth surface reduces the occurrence of porosity and cracks, as there are fewer stress concentration points. This increases the strength and service life of the parts. Without brush deburring, an uneven surface can lead to hot cracks or corrosion.
Workshop Practice & Handling Instructions
Use abrasive brushes with the correct grit (e.g., 120 to 320) and appropriate speed (approx. 500 to 1000 RPM). Start at the sharpest points and work slowly and continuously. Check the surface regularly for smoothness and remove only sharp burrs, not too much material. Use a liquid coolant to cool and remove debris.
