Gundrilling machines drill extremely straight holes in a variety of applications, including bar stock to prepare for rifle manufacturing.

Designed For:
  • Gundrilling
  • Holes up to 20 mm [0.80 in]
  • Hole depths up to 750 mm [30.0 in]
  • Round Workpieces

After gundrilling, reaming machines remove material from the inside bore surface, meeting roundness and surface finish requirements for production demands.

Designed For:
  • Reaming
  • Barrel calibers from .17 – .50
  • Firearms industry

Drilled and reamed bar stock becomes a rifle barrel blank with the servo-driven rifling process, performed with control and accuracy on R-series  machines. Button rifling is the last step before being turned and finished into high-performance rifle barrels.

Designed for:
  • Rifling
  • Barrel calibers from .17 – .50
  • Firearms industry

UNI machines BTA or gundrill a range of applications, including barrels, with the use of multi-spindle options, loading automation, and integrated robotics for high production environments.
