Rifling Methods Compared
Alternative Methods of Rifling
Hammer Forging
- Expensive capital investment
- Large space and infrastructure requirements
- Stress relieving required
Button Rifling
- Relatively modest capital investment
- Stress relieving required
Cut Rifling
- Relatively modest capital investment
- Very slow production rates
- Highly dependent on skilled operators
- Tooling needs to be maintained
Electro-chemical machined rifling
-
Nowhere near as expensive as hammer forging
-
Contactless machining does not induce any stress to the material so no requirement to stress relieve
-
Very low tool wear
-
Highly repeatable workpiece consistency
-
Excellent surface finishes in both the rifling and the lands
-
Very high production rates
-
Lower production costs with higher quality results
