This is another style of machining that uses electricity to make cuts—more specifically, holes. You’d want to opt for this when you’re set on creating a smooth, aesthetically pleasing surface finish, free of flaws. This happens through reverse electroplating (and it’s capable of cutting unique shapes and angles that other machines can’t. It’s a cold machining process, and it’s suitable for harder and less common metals like cobalt, rhenium, and other alloys.
