Half an airplane on the wall, a ten-foot metal dragon, and a full-blown recording studio might not scream “manufacturing efficiency,” yet Marathon Precision proves otherwise. Here’s how forging, ...

It doesn’t always have to be quite so violent though, as these experiments in electrochemical machining suggest. Electrochemical machining, or ECM, is not to be confused with electrical ...

Electrochemical machining (ECM) is well-suited for this challenging application. Barrels have different inner diameters, as well as rifling, which causes a projectile to spin and improves its ...
