Aluminum Drilling – Aluminum Fabrication with CNC Drilling

Aluminum is a malleable silver white metal, soft and lightweight, suitable for CNC machining. But for aluminum drilling, it has unique challenges. Due to the softness and ductility, aluminum makes constant prolonged contact with the cutting edges of a drill when cutting a hole or other shape, which would cause aluminum chips adhering to the drill and interfere new chips forming. To increase the effectiveness of Aluminum CNC drilling, proper application of coolant is essential, to move the chips from the cutting zone quickly. Drill holes on aluminum, HSS drill bits are enough. In addition, the suitable cutting edge angle for CNC drilling aluminum parts, right drill speeds and feeds, drill geometry and substrate, coolant application, tool coating, and more elements should be considered in CNC aluminum drilling. The top uses for aluminum are consumer products, transportation industry, and electrical power lines, CNC aluminum parts also have broad prospects in aerospace, construction, electricity, automobile, etc.
