Would you recommend building a CNC milling machine?
CNC converting a Sieg mill sounds a lot less challenging than building from scratch especially in the USA where there are companies supplying the parts at reasonable cost.
In UK parts are expensive so although it is still worth upgrading a Sieg or similar the cost savings are not so great. Currently the $/£ exchange rate is favourable so it can be worth importing items to UK even after paying import duty and VAT.
I expect to spend about as much again doing my conversion as it costs to buy a basic non CNC Taig mill.
Perhaps it would be useful to prepare a detailed budget based on cost of parts delivered to you.
I don't know what you intend to make but I wanted a high spindle speed of 10k rpm or more so the Taig scored points over the Chinese mills.
Best wishes
