Precihole 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 vise. Servo controls ensure precision indexing and pulling to cut grooves. The cycle repeats till the intended depth of grooves is reached. Typically, depth of cut is programmed to be about 0.004 mm 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.
