WTD: CNC Milling Machine for Alu & Steel

[dodgygeeza]

Those machines can hardly cope with machining wax, let alone any form of metal.

To be honest, if you are looking at machining anything harder than aluminium, then you are best looking at a mill.
Cutting steel needs much more torque and lower spindle speeds and a much more rigid machine than a traditional router design.
you would be best to get a 3 axis CNC mill and add two rotary stages to give you 5 axis, but you also need to consider the cnc controller as well.
Or get a second hand 5 axis machining center.

Have you evaluate the Chinese 3040 5 axis design that looks like a mill?

Just remember that you will need to pay shipping and VAT on top if bought on EBay
