ECM is the ideal technology for machining rifle barrels. Employing a special machine solution in the PI machine produces high-precision internal geometries on short and long barrels.

EMAG ECM now uses a clever technological concept developed specifically for rifling. First, where the tool is concerned, this means that the (very narrow and elongated) tool cathode generates the desired internal geometry of the barrel with high precision. A wide range of very different geometries are possible, for example “polygonal,” “progressive” or “standard rifling.” Within the machining area, there are eight of these cathodes inside a compact module.

It is faster than the fre ...
