The 2021 Unisig R-Series 3 Machine Barrel Processing Cell is a turnkey, three-machine cell built for high-precision barrel manufacturing workflows, combining a dual-spindle UNE12-2-750-CR Gundrilling Machine, a single-spindle R-2A Rifling Machine, and a semi-automated robot-driven handling and inspection cell. The gundrilling station accommodates diameters from 0.055 inch to 0.50 inch with up to 30 inch depth, outfitted with whip guides, a Siemens UNISIG PLC system, magnetic chip conveyors, programmable coolant, and automation readiness. The rifling machine supports up to .50 caliber diameter and 40 inch rifling depths inside a fully enclosed, guarded system. Rounding out the system, the automated handling cell integrates Fanuc I/O, collision-safe robotic placement, inspection stations, and both infeed and outfeed operations with built-in air blast and sealing functionality. When compared to traditional manual barrel cells or gundrill-only platforms, the R-Series delivers superior automation, improved coolant management, and seamless integration between drilling, rifling, and handling—minimizing operator intervention and significantly reducing cycle time for premium firearms manufacturing.
