Precise Deburring for Accurate Shots from Sporting Firearms
Absolute precision is the driving force behind every sport shooter. The challenge is to be able to make accurate shots with their firearm even at long distances. This requires, on one hand, extensive experience and skill from the shooter, and on the other hand, the best and above all highly precise “equipment.”
Producing Burr-Free Internal Threads
To enhance the accuracy of long guns (rifles), so-called "muzzle brakes" are used, which are mounted on the barrel to redirect the gases generated during firing and thereby reduce recoil.
The manufacturer "deecee precision GmbH" has introduced the "Sinus Brake," a highly precise muzzle brake that combines optimal precision, recoil reduction, and gas redirection.
Angled bores in the first baffle redirect the gases away from the shooter, providing a more comfortable shooting experience compared to competing muzzle brakes. The additional "Barrel Tuner" optimizes vibration behavior during firing through its weight and numerous adjustment options. This allows the weapon to achieve maximum precision.
To guarantee this shooting precision, all components must be manufactured with high accuracy—including the "Sinus Brake." The fully CNC-machined individual components "Made in Germany" must also be deburred mechanically to ensure consistent quality. Deburring the M4 thread used for clamping on the inside of the "Barrel Tuner" proved to be a relatively delicate task. Since any burr on the inside could cause significant damage during assembly, the thread of the main bore had to be produced completely #burrfree.
Contour-Accurate Tracing of the Thread Exit
Only the Back-Burr Cutter & Path deburring system from KEMPF could guarantee burr-free and process-reliable manufacturing. The Back-Burr Cutter BXC-28-A, with a head diameter of 2.8 mm and a stepped shank, enables contour-accurate tracing of the thread exit together with the specially generated NC data set, ensuring that all burrs are removed directly in the CNC machine. Even when machining stainless steel, the constant offset of the milling cutter’s cutting point relative to the component results in exceptionally high tool life.
