  • The DeHoff G560-DR2 performs both gundrilling and reaming operations on gun barrels. After first gundrilling the barrels, a quick tooling changeover allows a pull-reaming operation to be performed using the same machine. The twin-spindle machine has a barrel capacity of 17 to 50 caliber and a slide travel of 60 inches (1524 mm).

    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-DR2, such as a high-pressure coolant system, Beckhoff controls, and a full machine enclosure. 

    The G560-DR2 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.

  • The Eldorado KM75-48 is a 3-axis gundrilling machine used to manufacture products like transmission shafts, manifolds, and mold matrices. The machine includes updated Beckhoff controls with G-Code programming, which provides enhanced flexibility. Complex gundrilling operations can be performed with a single fixturing setup.

    The KM75-48 features a “knee” fixture table to provide 3-axis CNC gundrilling capability. Drill capacity is 0.078 to 0.75 inches (1.98 to 19.1 mm). Drill slide travel in the Z-axis is 48 inches (1219 mm), with table travel of 24 inches (610 mm) in the X-axis and 12 inches (305 mm) in the Y-axis. 

    The machine has a durable design that incorporates hardened and ground box ways and hand-scraped mating components (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 KM75-48, such as the F18 high-pressure coolant system and a machine enclosure.

  • The redesigned DeHoff 2072TC is a gundrilling machine with 5-axis capability. The gundrilling spindle is mounted on a traveling column to provide the X-axis and Y-axis movement. A CAT 40 spindle is also mounted on the traveling column to enable secondary operations like milling and tapping. The machine is ideal for drilling complex hole patterns, like those seen in heat exchangers, manifolds and molds.

    The 2072TC has a 2-inch (50.8 mm) gundrilling capacity and a 72-inch (1829 mm) slide travel. The traveling column provides 60 inches (1524 mm) of X-axis travel and 46 inches (1168 mm) of Y-axis travel. Workpiece fixturing options include a stationary T-slot table and a rotary table with self-centering hydraulic vises. The rotary table provides B-axis rotation, and is mounted on a W-axis slide to provide clearance when rotating a long workpiece. Load capacity for the entire work table is 9,000 lbs (4,082 kg).

    The machine features 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 accuracy and surface finish. Standard elements are also included on the DeHoff 2072TC, such as a high-pressure coolant system and Beckhoff controls with G-Code programming capability. 

    DeHoff multi-axis gundrilling machines are built-to-order by Kays Engineering in their Marshall, Missouri facility. To learn more please visit www.kays-dehoff.com/dehoff/multi-axis.

  • DeHoff G560-R2
    Extended Travel for Gun Barrel Reaming Machine...

    • 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.

  • Eldorado M30-30T
    Twin-Spindle Gundrilling with Independent Spindle Control...

    • The Eldorado M30-30T is a twin-spindle gundrilling machine with independent spindle control, which allows the machine to perform two independent drilling cycles at the same time. A separate 6.5” (165 mm) full-color control screen is installed on both sides of the machine to enable the operator to take full advantage of the independent spindle flexibility.

    The M30-30T has a 5/16” (8 mm) diameter drilling capacity and a 30” (762 mm) maximum drilling depth. It features precision ground ball screws and high speed cartridge spindles to improve drilling performance. The machine also incorporates flame-hardened and ground cast iron box ways and hand-scraped spindle housings (instead of linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved hole accuracy and surface finish.

    Eldorado gundrilling machines are designed and built by Kays Engineering in their Marshall, Missouri facility. To learn more please visit www.kays-dehoff.com/eldorado/m30.

  • DeHoff G536-C1
    New Gun Barrel Single-Point Cut Rifling Machine...

    • The new DeHoff G536-C1 is a CNC machine used to “cut” rifling grooves into gun barrel blanks, and is an alternative to button rifling. Since the cut rifling process creates the rifling groove using a single-point cutter instead of via deformation, it does not induce any additional stresses into the barrel. The G536-C1 is the first fully CNC programmable single-point cut rifling machine commercially available for sale in the U.S.A. 

    The G536-C1 can perform cut rifling on barrels ranging from 22 to 50 caliber and from 4 to 30 inches (102-762 mm) in length. Twist rates range from 1 rotation every 4” (102 mm) to 1 rotation every 60” (1524 mm). The machine provides the ability to cut rifle at variable twist rates along the length of the barrel, also known as “gain twist”. Other programmable operations include traverse rate, depth of cut, and number of grooves.

    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 accuracy.

    DeHoff rifling 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.
