What would you repair of the alloy wheels?

I dont see what CNC machine you need there and for what purpose exactly???

What you need for this business is: an alloy wheel straightener /hydraulic manual or automatic computerized machine/ , propane torch, infrared thermometer, disc grinder, orbital sander, orbital polisher , arc welder or tig welder. Oops, and a hammer .

I have looked into that business, when i hacked my alloy wheels and there was nobody around to straighten it. With the above said, i can repair any repairable alloy wheel problem.
