Leave nothing to chance, use Electrochemical – EC Rifling for state-of-the-art rifling, improved productivity, and outstanding quality.
the USA for more than two decades.
At Deburring Expo we will introduce a new machine and tools for static and dynamic ECM corrugating.
Watch the 3D animation explaining static and dynamic EC corrugation. It is available on the Extrude Hone Virtual Booth https://vb.extrudehone.com/en/ under the General Engineering Application Corner Video Gallery.
The machined barrel gives the bullet a rotational motion when fired. Rifling applies to rifles and handguns.
Mechanical rifling is anything but a perfect process.
Input bore condition when reamed, average Ra 0.4µm (16µin). The length of the barrel determines the possible EC rifling solution, either static or dynamic.
A high-precision twisted cathode was developed and machined. Static cathodes can be up to 160 mm long, while the shortest movable cathode sections are used for long tube EC-Dynamic applications.
The cathode creates the final design inside the barrel during the electrochemical machining process.
Processing a handgun barrel takes approximately 23 seconds.
The best barrel for greater precision. Don’t leave anything to chance. Use Extrude Hone’s Electrochemical Process – EC Rifling.

The Science Behind
EC rifling leverages the dissolutions of the material and is governed by Faraday’s law of electrolysis.
The mass of a metal dissolved is proportional to the quantity of electrical charges transferred to the electrode.
