Rifling is the term for helical grooves machined into the internal surface of a firearms 's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves.

模头挤压法（button rifling）在1950年代由美國雷明頓公司工程師麥克·華克（Mike Walker）發明的膛線製法。 其方法是先將槍管鑽一個比 膛徑 （bore diameter）稍小的洞，然後用一根上面有跟陰膛線對應突起的高硬度模頭（button），用高壓機器從洞中邊轉邊壓下去，將 ...

现代制造枪管来福线的方法，多用来制造多角型来福线（polygonal rifling），适合大量生产枪管，由德国在1930年代发明。 它的作法是将枪管钻一个比阴膛直径（groove diameter）稍大的洞，将一根和枪管内膛形状相反（阴来福线位置突起）、贯串整根枪管的高硬度模杆放在洞中，然后以机器在枪管外锤打，把钢材挤到紧贴模杆，然后将模杆抽出，模杆突出的地方所压出的就变成阴来福线了。 速度最快、成本最低的方法，不过由于巨额的初期设备投资，仅有少数枪管制造 …

Cut Rifling: 切削式产生来复线。 使用单一钩状切刀， 慢慢的、一条一条的制出来复线，是最早的生产方式。 如今只有最精密，最高级的枪管以此种方式生产。

Oct 19, 2023 · Rifling refers to the spiral (helical) grooves that are cut or swagged on the internal surface (bore) of a gun barrel, which helps impart the spinning motion to a bullet when it’s fired. A spinning bullet is found to be more stable in its trajectory, and is therefore more accurate than a bullet that doesn’t spin.

The purpose of rifling is to impart a spin to a projectile as it is thrust through the air in order to stabilize it and allow it to be more accurate.

Rifling consists of spiral grooves cut into the inside of a barrel of a gun. [1] . It causes the bullet or projectile to spin as it flies through the air. This greatly improves the accuracy of the bullet over longer distances. [2] . The first muskets to use this technology were called rifles. [2] . Barrels are rifled using a left or right twist.

May 21, 2023 · Rifling takes the form of one or more lands and grooves of differing widths, profiles, arrangements and twist (turn) rates. The spiral depressions in the bore surface between the lands are...

法语 单词 rifler 就 曾经 有 “ 刮 ” （scratch） 的 意思， 这 也 就 解释 了 为什么 枪膛 内 的 膛线 被 称为 rifling。 3. Groove on the inside of the barrel, rifling, spin the ball towards its target. 枪管 内 壁 的 凹 槽 即 装 膛线， 让 子弹 旋转 着 射向 目标。 4. News that the Taliban were rifling through the documents to mete out revenge killings exacerbated those fears.

Aug 19, 2016 · These grooves became known together as “rifling” and they are a key technology in modern rifle (as the name suggests) and pistol barrels. Rifling works by spinning the projectile about its axis, causing gyroscopic forces that spin-stabilize it throughout its flight; tighter rifling will spin a bullet faster, while looser rifling will spin a ...
