Aluminum Welding on Countersinks? Non-Sticking Solutions
Expert analysis of Aluminum welding on countersinks causes with Lihao Technology exclusive solutions
🔍 Cause Analysis of Aluminum welding on countersinks
1. High Aluminum Adhesion
Aluminum is ductile and welds onto the cutting edge, forming a built-up edge
2. High-Friction Coating
Standard coatings have high friction - chips stick to the tool surface and clog
3. Improper Cutting Parameters
Low speed or feed raises cutting temperature, increasing welding
✅ Lihao Technology Solutions
TiAlN Composite Coating
0.15 friction coefficient - smooth, non-sticking, ideal for aluminum
Mirror-Polished Edges
Ra0.4 mirror polish - chips slide off, less built-up edge
Large Rake Angle Design
15-degree rake cuts sharp and cool, reducing welding
High-Speed Cutting
Recommended 3000-5000rpm - cool high-speed cutting evacuates chips fast, no welding
