UNR Reaming Machines
UNISIG’s flexible UNR series reaming machines are an integral step in the manufacturing of rifle barrel blanks. Performing reaming after gundrilling using a UNR series machine produces an extremely round, accurate bore. Reaming further improves the finish achieved during gundrilling to make barrel blanks ready for rifling.
UNR series machines are available as exclusive reaming machines for three-machine rifle barrel production cells, and as combination gundrilling and reaming machines for two-machine production cells.
