Precihole CRVN Series – Cut Rifling Machines
Precihole is one of the few machine manufacturers in the world that builds a cut rifling machine. Precihole’s Cut Rifling Machines produce extremely accurate and precise barrels by cutting grooves using a single point cutting tool. The workpiece is clamped rigidly in a self-centering vice. Servo controls ensure precision indexing and pulling to cut grooves. The cycle repeats until the intended depth of grooves is reached. Typically, depth of cut is programmed to be approximately 0.004mm or 0.00015″. This rifling process can be used where very high precision and repeatability are required in the barrel for a weapon system like a sniper rifle or a match gun. This process is capable of rifling conventional grooves or 5R rifling grooves and can handle progressive or gain twists.
