I would use it mainly for milling on extruded aluminum enclosures. In particular for cutting out area in cover for LCD display and slits on ends for switch or connectors. Aluminum is approx 1.4 to 1.8 mm thick.
I was looking at some inexpensive models on Amazon (< $500) . They say they will mill aluminum but I wonder how many passes it would take to cut through. I'm not against spending up to $2k if it would buy something worthwhile.
The work area I may need could be 12"x12"x4" for example. So I would like to hear from those that may have something like this, use it, recommendations and any pros and cons.
