Precision plays a decisive role in the manufacture of weapons. One technique that contributes significantly to the precision of firearms is rifling – the insertion of helical flutes into the barrel of a weapon. The rifling ensures that the bullet rotates when fired and hits its target with precision. Traditionally, rifling used to be produced by mechanical processes such as hammering. Or button broaching. However, with the further development of technology, electrochemical machining (ECM) is establishing itself as a superior alternative that enables much greater precision.
ECM is an innovative technology for machining the barrels of sporting guns. A special rifling module is used in the PI machine. The result is a highly precise and homogeneous field rifling profile for short and long barrels.
