Precihole is proud to be in a very small elite group of machine manufacturers in the world that can provide a broach rifling machine for medium and large caliber weapon systems. Broach rifling creates spiral grooves in the barrel using a hook cutter. The linear and rotary motion of the hook cutter are precision controlled for accuracy using a servo drive and ball screw or rack and pinion mechanism. The broach cutters are progressive in size, and each cutter cuts a size slightly bigger than the previous one.
