Four-Spindle Gundrill Runs Unattended

The DeHoff G548-D4 from Kays Engineering is a four-spindle gundrilling machine designed for high-volume production of gun barrels. It automatically loads and unloads the barrels for unattended machining. As many as 48 barrels can be pre-loaded into the magazine holder. Lift-and-carry automation loads barrels in and out of the fixturing.

Four gundrilling spindles offer a barrel diameter range of 17 to 50 caliber and a maximum barrel length of 27" (686 mm). The machine has a cast iron drill head base with steel boxways as well as a hand-scraped and fitted saddle, gibs and straps. These features damp vibration and prolongs tool life.
