EMAG ECM is showcasing its cutting-edge electrochemical rifling process at the IWA OutdoorClassics 2026. This innovative approach addresses the high demands of precision, process reliability, and reproducibility required in the production of rifling profiles for gun barrels. Traditional methods often hit technical and economic limitations, a challenge EMAG’s technology aims to overcome.
The electrochemical rifling involves a tool cathode creating the barrel’s internal geometry without physical contact, avoiding thermal or mechanical stress on the workpiece. This method allows machining of even high-strength, tempered alloys, irrespective of material hardness.
Key technical advantages include the absence of thermal edge zones, microcracks, and distortion. The process supports geometric diversity, enabling standard, polygon, progressive, gain-twist, and hexagonal profiles. Up to eight barrels, each ranging from 50 to 800 mm in length, can be machined simultaneously. It promises short setup times and minimal tool wear, coupled with lower capital investments compared to traditional forging techniques like hammers. Users benefit from high repeat accuracy, ensuring consistent ballistic properties.
Renowned rifle and pistol manufacturers in Europe and the USA have successfully adopted this technology. EMAG’s ECM Rifling not only enhances shooting accuracy but also boosts competitiveness in series production.
Attendees at IWA OutdoorClassics 2026 can witness this advanced technology at booth 3-133 in hall 3, where EMAG ECM representatives will be available for expert consultations.
