Feeds and Speeds
Aluminium machines faster than most metals, but optimal results require careful parameter selection. For 6061-T6, start with a surface speed of 800-1200 SFM with carbide tooling. Higher speeds produce better surface finishes but require adequate chip evacuation.
Tool Selection
Use 2-3 flute end mills designed specifically for aluminium. High helix angles and polished flutes prevent chip welding and ensure consistent finish quality.
