Precihole BRM Series – Broach Rifling Machines
Large Artillery Barrel Solutions
Precihole is proud to be in a very small elite group of machine manufacturers in the world that can provide broach rifling machines for large caliber weapon systems. Broach rifling creates spiral grooves in the barrel by removing steel 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. The fine filtration system on the machine ensures that the system gets coolant at requires rates and the swarf is evacuated properly from the barrel.

The broach rifling tool is at the forefront of precision in manufacturing firearm barrels, offering a range of benefits:
Exceptional Accuracy
The use of broach rifling ensures utmost accuracy in creating grooves within barrels. This accuracy is key to the enhanced performance of firearms, making broach rifling a preferred method for quality-focused manufacturers.
Increased Barrel Longevity
The uniformity and finesse achieved by a rifling broach contribute to an extended barrel life. This method reduces wear and tear, ensuring consistent firearm performance over extended periods.
Consistent Outputs
Broached rifling is renowned for its ability to produce consistent results. This consistency is essential for manufacturers who value uniformity and quality control in their production process.
Efficient Manufacturing
Compared to other methods, broaching firearms is remarkably efficient. It allows for machining complex patterns in a single pass, significantly reducing production time and costs.
Design Flexibility
Broaches for firearms offer the flexibility to create diverse groove patterns and sizes, meeting various design requirements and catering to a wide array of firearm types.
Customization and Specialization
The process allows for significant customization. Manufacturers can easily modify the broach tool to create unique rifling profiles, addressing specific market needs with a custom broaching machine.
