Routing aluminum

Aluminium is lightweight yet very strong, making it extremely suitable for many different applications. Aluminium is easy to machine with a CNC router, it is versatile and has high durability.


Aluminium is divided into different groups (NEN-EN 573 standard) based on the main alloying elements. When choosing an aluminium alloy for a particular application, it is important to know to what extent formability, weldability, electrical conductivity, ductility or anodisability play a role. Ask your aluminium supplier for a variant that mills well. (For example, AlMg3 or AlMgSi1.)

Tip: When routing aluminium, use a 3D inlet so the cutter runs sideways with the cutting edge into the material. That way you avoid a build-up of debris under the tool.
Coolant is preferred, but some aluminium alloys can also be dry-milled.

Depending on machine and spindle power, other values may apply.
