SOLUTIONS FOR GUN BARREL MANUFACTURING GUNDRILLING, REAMING, AND RIFLING WE MAKE COMPLEX PROCESSES SIMPLE.

Nobody builds rifle barrel production equipment like UNISIG. Before UNISIG, fully automated barrel production was only possible for the largest firearm OEMs. Now, UNISIG has opened the door for small to mid-sized as well as very large manufacturers by developing scalable barrel production cells, designed for productivity and reliability. UNISIG SOLUTIONS FOR THE FIREARMS INDUSTRY UNMATCHED INDUSTRY EXPERIENCE Our 40 years of experience building high volume production gundrilling and machining systems is unmatched in the industry. UNISIG holds a unique position as a leader in firearms...

GUNDRILLING, REAMING, AND RIFLING SOLUTIONS FOR GUN BARREL MANUFACTURING MODERN BARREL MANUFACTURING Rifle and pistol barrels have been produced for over a century and can be manufactured using common machine shop equipment and tooling. Industry organizations have now standardized dimensions, which are publicly available, so anyone interested in gunsmithing can make gun barrels. Our machines are designed and built for high volume production and maximize the potential of existing tools. We integrate automation for improved efficiency which provides the ideal updated environment for...

FEATURES • Very high accuracy machine base, machined on all sides in a single set-up • Counter-rotation of tool and workpiece for extreme concentricity • Servo driven work headstock for precision adjustment of part length and clamp force • Programmable coolant system delivers the optimum flow to the drill tip to benefit chip evacuation • Full enclosure for clean floor, quiet operation, and safe work environ

REFRIGERANT CHILLER Precise temperature control regardless of ambient temperature. 7

OPTIONAL GUNDRILL CONVERSION Available on twin-spindle machines, this option allows the machine to be changed between reaming mode and gundrilling mode, with counter-rotation, within a single machine. AUTOMATIC TOOL RETURN Auto-pull reaming tool return eliminates manual tool intervention, improving throughput. It is also essential to building a fully automated barrel production cell. 8

DRAG FLIGHT CONVEYOR Elevates reamer fines and gundrill chips into hopper without operator effort. 9

WORKPIECE CONVEYOR - THROUGH FEED 4-spindle machines produce a lot of blanks every shift. The smart conveyor system allows single-pieceflow and maximizes spindle uptime. This option works with a manually loaded machine as well as being compatible with robotic automation. ROBOT READY OPTION As you grow, meet increased volume and reduce operation time by incorporating robot-ready options to your production cell. 10

BUTTON RIFLING MACHINES 1-2 SPINDLE MANUALLY LOADED MACHINES Manual workholding is simple and reliable. The workpiece is clamped in a 3-jaw chuck, centralizing the workpiece to the machine centerline. A thrust bushing offsets the pull force which eliminates extreme effort when tightening the workpiece.

GUNDRILLING, REAMING, AND RIFLING SOLUTIONS FOR GUN BARREL MANUFACTURING Number of spindles Max pull force Rifling diameter max. Part length max. PERFORMANCE Tool spindle speed maximum AUTOMATION READY MACHINES Rifling machines in automated cells require an automatic clamping system for the workpiece, and an automated tool return for the rifling button. UNISIG automated rifling cells standardize these loading features.

CNC RIFLING MACHINES CUT & BUTTON RIFLING CNC VERSATILITY The R25 servo-rifling machines are CNC controlled to allow the user to develop their own unique rifling profile. Quantity of grooves, groove depth as well as straight or gain twist grooves can all be programmed from the machine control. BUTTON RIFLE
