They are used for deep drilling—a depth-to-diameter ratio of 300:1 or more is possible. A mistake or machine malfunction at the end of the process can prove wasteful. In order to find out which method of rifle barrel manufacturing was best, I interviewed Jochen Anschutz (president of Anschutz) and Woody Woodall (president of Lothar-Walther). • Once a manufacturer chooses a rifling process, the class characteristics of the weapon’s barrel will remain consistent, each will have the same number of lands and grooves, with the same approximate width and direction of twist. For over a century, Shaw O.E.M has been designing and manufacturing precision-crafted gun barrels for virtually every small arms manufacturer in the country. Hand Finished . U.S.A. –-(Ammoland.com)-DC Machine is the biggest machining company you may never have heard of. Production history Manufacturer Colt's Manufacturing Company: Produced 1955–1996 Variants 2.5-inch (6.4 cm), 3-inch (7.6 cm), 4-inch (10 cm), 6-inch (15 cm) and 8-inch (20 cm) barrel Specifications Weight 38 ounces (1.1 kg) to 48 ounces (1.4 kg) Cartridge.357 Magnum: Action: Double-action: Feed system Six-round cylinder: Sights Rear adj. Sassen are UK’s leading manufacturer of bespoke gun barrels with international partners. learn more. Because semi-auto RPD variants are manufactured using de-milled parts kits from full-auto RPD machine guns, in order to comply with ATF regulations the full-auto parts must be modified such that the resulting semi-auto rifle cannot be readily converted into a machine gun. Tank gun barrel forgings; Self-propelled howitzer forgings; Naval guns; Helicopter and aircraft barrels ; Mortar barrels; Increasing system life. The R-2A rifling machine uses servo-drives and button rifling to press grooves into the blank with ultimate precision and control. Bluing is a passivation process in which steel is partially protected against rust using a black oxide coating. In general, this information is … None of the page scans are of original documents but are simply transcribed information typed into a word processing program. This method has many advantages compared with the convantional methods; cutting (broach rifling), button rifling, forging and electrochemical rifling. Choose the type of steel to be used for the gun barrel. Once rifled, we subject the barrels to a number of processes to ensure the stability and accuracy we are known for. manufacturing process. 2019 Impact Factor. 3.046 Materials and Manufacturing Processes. By nature of the process, the steel is hardened through a thermochemical treatment to the steel which makes the steel harder and resistant to water penetrations. UNISIG’s UNR reaming machine is combined with precision gundrilling, to perform two processes on a single machine. o Accept more and more powerful ammunitions . We use the button rifling process in order to achieve maximum precision and rigidity of our barrels, no matter if … A cathode rod rifling assembly is mounted in the pressure chamber in axial alignment with the gun barrel. Some metal alloys can not be cut. Our O.E.M Division is the oldest, most experienced independent barrel manufacturer in the United States. Barrels: Beyond the receiver, the key to a rifle's accuracy is its barrel. The paper discusses a gun barrel of a possibly late 15th-early 16th c. date from the collection of the Castle Museum in Malbork (Marienburg), Poland (MZM/468/MT). Cut-rifled barrels must be lapped. manufacturing processes in its capability to produce a diversity of part geometries and geometric features Casting can also produce a variety of shapes, but it lacks the precision and accuracy of machining ©2002 John Wiley & Sons, Inc. M. P. Groover, “Fundamentals of Modern Manufacturing 2/e” Classification of Machined Parts 1. The steel chosen must have a strength of 100,000 psi (689476 kPA) to withstand the force of the gasses that propel the round. The additive mainly comprises methyl sulfonic salt, sodium bromide and magnesium sulfate, and the plating solution mainly comprises CrO3, H2SO4, Fe3+ and Cr3+. Our commitment to quality craftsmanship is the reason our products have stood the test of time. They are produced from 4150 gun-certified chromemoly steel, double stress relieved at the steel mill, and cryogenically treated. Gun statistics for the manufacturing and production of firearms reveal that the gun market is unique in structure and fundamentals. Inspection. It increases the velocity of your barrel by a few hundred feet-per-second and slickens the surface to make your gun extremely lubricated. This video shows the process of cut-rifled barrel-making by one of the world's best barrel manufacturers. In one embodiment of the apparatus, an elongate pressure chamber for receiving electrolyte fluid under pressure is mounted in alignment with an anode gun barrel and in fluid communication therewith. Unlike most industries, the gun market is not susceptible to recessions or changes in technology, but solely, to government intervention and the adoption of more stringent gun laws. Consecutively manufactured EBIS barrels with the same EBIS pattern are significant to the study because these barrels will be manufactured with the same EBIS equipment/tools and exhibit a similar pattern.
