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 a rotary encoder to interpolate linear and rotary motion—producing rifling twists exactly as needed by the rifling tool. Machine features include load monitoring that graphs the rifling pull load on the HMI. The operator can monitor the rifling operation on-screen, output to printer or storage disk if required.?

  • Use of hydraulic cylinder and servo drives for interpolation of linear and rotary motion
  • Precision chuck for barrel location and clamping
  • Use of specially formulated rifling oil for optimized heat dissipation and spring back of metal
  • Mitsubishi / Siemens PLC controls with touch screen HMI
  • User-friendly screens, graphing and simplified machine operation
