I do this type of work as well and I use a Sherline 2010-CNC mill with CNC Rotary table.
To command the machine, I use Mach-3 software. cheap and very easy to use and set-up.
To convert the CAD drawings into mill programs (post processing), I first used Lazycam, but as I went into more complex milling, I bought Deskproto.
Hope this helps you!
