Button Rifling Machines by Precihole incorporates the latest features to form precision grooves in small caliber weapon systems. The rifling button is pulled and rotated precisely through the barrel. Precision in rifling is critical. 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. Machine features include load monitoring that graphs the rifling pull load on the HMI. Operator can monitor the rifling operation on screen, output to printer orflash disk if required.
