The UNISIG R-4-2-2 fully automated barrel cell provides continuous and synchronous production.
Automation such as robots and conveyors can be machine mounted or used to combine multiple machines or operations.
In operation, the UNISIG R-4-2-2 production cell uses a smart conveyor to simultaneously load four barrel blanks into a UNI four-spindle gundrilling machine. Drawing from a bulk feeder, this automated loading is the starting point for many hours of unattended operation. The four gundrilled parts are moved out of the machine by the conveyor, and a 6-axis robot then loads two gundrilled parts into the UNR reaming machine.
After precision reaming, the robot transports the two gundrilled and reamed barrels to a blow-off station and then loads them into the R-series rifling machine. Gundrilling, reaming and rifling operations are happening simultaneously for maximized productivity. The robot then delivers finished, rifled parts to a multi-level discharge magazine.
Prior to UNISIG, such fully automated barrel production was only possible for the largest firearm OEMs, according to UNISIG CEO Anthony Fettig. Now, production cells like the R-4-2-2, open the door for small to mid-sized as well as very large manufacturers by developing scalable barrel production cells, designed for productivity and reliability.
