Just wanted to mention for anyone that might need 3 phase power in a home environment, there are ways to convert 120/240 "single phase" power to, for example, 208 or 480 volt 3 phase power if you have a need and don't require too much horsepower, and at a cost of much less than the $20,000 that someone mentioned as the cost to get it installed by a power company.
One is a motor / generator set, with a 240/120 volt single phase motor driving a 3 phase generator at, for example, 208 or 480 volts. Another is a static device known as an "add-a-phase". In the case of the motor / generator set, in most cases you won't achieve 60 Hz., but instead something less than that, but, even machine tools with gearing (or electronics) to do things like match a feed rate to a rotation rate (to cut threads) should be able to handle that (mechanical gears will maintain the proper ratio) or be modified to handle that (I would expect that an electric feed device either already has the components to detect the main motor speed and adjust the feed rate or be able to be modified to do so. There is a limit to how big a machine(s) you can handle this way -- if you can provide say a 40 amp feed from a 240 volt single phase circuit, that is about 10 kw and maybe 13 Hp. -- a motor generator set with a 13 Hp. motor should be able to drive a generator to handle something like a 10 Hp. 3 phase motor (or more, depending on the efficiencies and the required starting current).
