Aluminium profiles are very convenient and easy to work with small to medium scale CNC machines. It is rigid enough for all purpose wood or mild steal working CNC machines. However if you plan to work with strong steels, aluminium profile frame structure might not strong enough for your CNC machine.

Aluminium is durable, lightweight, ductile and malleable metal. Aluminium is the most widely used non-ferrous metal and also naturally generates a protective oxide coating and is highly corrosion resistant. Aluminium is an excellent heat and electricity conductor. Aluminium is non-magnetic and non-sparking. Aluminium is 100% recyclable without any loss of its natural qualities. Due to this benefits it’s good idea to use Aluminium profiles for your DIY CNC machines.
