Burrs on Chamfers? Causes and Solutions
Expert analysis of Burrs on chamfers causes with Lihao Technology exclusive solutions
🔍 Cause Analysis of Burrs on chamfers
1. Insufficient Tool Hardness
Standard HSS below HRC62 wears fast on hard materials like stainless steel, creating burrs
2. Dull Cutting Edges
Poor grinding leaves micro-nicks that tear material and create burrs
3. Improper Cutting Parameters
Speed too low or feed too fast makes cutting unstable and forms burrs
4. Poor Tool Coating
High-friction coatings clog chip flow; chips scrape the hole edge and cause burrs
5. Inaccurate Tool Angle
Loose angle tolerance causes uneven cutting and burrs
