The DeHoff G560-B1 is a custom machine designed to form the rifling grooves in gun barrels. The barrel is rotated by a 3-jaw chuck while a rifling button tool is pulled through the barrel by a hydraulic cylinder. The button tool deforms the rifling grooves into the internal bore of the barrel using a swaging process. All the rifling grooves are cold-formed in a single pass.
The G560-B1 can machine barrels from 17 caliber up to 50 caliber, and has a slide travel of 60” (1,524 mm). It features a pneumatically-operated chuck with programmable “twist rates.” The rifling twist rate, which is the distance the rifling takes to complete one full revolution, is variable from 1 turn in 5” (127 mm) to 1 turn in 60” (1,524 mm). The twist rate, pull speed and pull force are all programmable via the Beckhoff control.
The G560-B1 is part of a turn-key package of gun barrel manufacturing equipment offered by DeHoff, including machines for gun drilling, pullreaming, button rifling, cut rifling, as well as tooling, stress relieve ovens and air gauging equipment. DeHoff machines are built-to-order by Kays Engineering in its Marshall, MO, facility.
