The DeHoff G560-R2 is a twin-spindle pull-reaming machine used to manufacture gun barrels. It has an extended slide travel of 60 inches (1524 mm), which is 25% more than the previous model offered by the company. It can accommodate barrel sizes from 17 to 50 caliber, with automated loading/unloading of barrels.
The machine features a durable, heavy-duty design that incorporates a cast iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs, and straps (versus linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved hole accuracy and surface finish. Standard elements are also included on the G560-R2, such as a high-pressure coolant system, Beckhoff controls, and a full machine enclosure.
The G560-R2 is part of a turnkey package of gun barrel manufacturing equipment offered by DeHoff, including machines for gundrilling, pull-reaming, button rifling, cut rifling, as well as tooling, heat treat ovens, and gaging equipment. DeHoff machines are built-to-order by Kays Engineering in their Marshall, Missouri facility. To learn more please visit www.kays-dehoff.com/dehoff/gun-barrel.
