Hello, I'm looking to build a CNC machine to mill Aluminium and Brass.
What Spindle should I use a 1.5KW or a 2.2KW? The 2.2KW is more powerful but is it overkill?
Both spindles can can cut aluminium, brass and other non ferrous metals. The 2.2kW is recommended for more industrial style machines and would be overkill for smaller non industrial kits.
The 1.5kW spindle is recommended as it is a very popular spindle that is used in milling aluminium, brass and copper.
Kind regards
Tawanda
