Precihole BRVN Series – Button Rifling Machines

View full gallery

Precihole Button Rifling Machines incorporate the latest features to form precision grooves in small caliber weapon systems. The rifling button is pulled and rotated precisely through the barrel. The machine uses anti-backlash helical guides and rotary encoder to interpolate linear and rotary motion. This produces rifling twists exactly as needed by the rifling tool. Precihole’s button rifling operations are extremely fast at pull feeds of 40-50 IPM.

Machine Features:

  • Robot readiness for integration in an automated cell
  • Automation for insertion of rifling button and retrieval back to original position
  • Auto barrel clamping and unclamping
  • Auto lubrication of tool and barrel for smooth operations
  • Customized screens with graphing for operator-friendly usage
