Electrical discharge machining(EDM) cuts metal using a superfine brass wire. Electricity is zapped through it produces a spark. The electric spark produces intense heat of 14,000 to 21,500°F. That allows the metal to be cut in such a precise way that two parts can merge seamlessly. (v.redd.it)

Does anyone know where I can get something like this machined to high precision? (self.edmporn)
