Application of Spinning in Military Industry
With the development of international defense industry, spinning technology has been widely used. It is extremely important to consequently metal spinning I also got a lot of attention and wanted to join the ranks. https://www.richspinning.com
improve the reliability of integral seamless parts such as rockets and missiles, avoid failures and accidents, and reduce weight.
The welds of large-diameter thin-walled shells are prone to brittle cracks and stress concentration, which is not suitable for the requirements of
thinning the wall thickness, reducing weight, improving strength, reducing annular welds, and eliminating longitudinal welds of large shells.
Spinning can make up for these shortcomings. The accuracy of missile hits is closely related to the manufacturing accuracy of its missile body.
The use of spinning technology can process missile bodies that meet the accuracy requirements. Some parts of rockets and
missiles are made of high-temperature materials such as tungsten, molybdenum, tantalum, and niobium, which are difficult to process by other methods.
Only heated spinning can complete the processing.
The application of spinning technology in the aerospace and aviation industries of developed countries highlights its advancement, practicality and economy.
The spinning parts that can be used in missiles are shown below. As can be seen from the figure, many rotating parts in missiles,
such as nose cones, fuel tank bodies and heads, engine casings, nozzles, etc., can be processed by spinning.

The United States initially used the roll welding method to manufacture large rocket engine shells, but cracking occurred during the test,
resulting in accidents and failures. Later, it switched to high-power spinning processing to produce an integral seamless shell,
avoiding the occurrence of this problem and showing the obvious advantages of the spinning process.
Now the United States can spin high-strength steel solid rocket engine shells with a diameter of 3000mm and a length of 6m, ¦Õ4000mm and a length of 6m,
which are used in the “Minuteman” and “Polaris” missiles. Many spinning parts are used for missile nozzles, nose cones and fuel tank heads.
American aircraft and its engine manufacturing companies are equipped with metal spinning machines for processing aviation parts
, such as jet engine turbine shafts, combustion chamber cones and bushings, compressor casings, engine bearing housings,
tube tail cones and bomb rack tail cones. In addition, many aerospace and aircraft parts are processed by spinning.
In addition to the above-mentioned aviation and aerospace industry applications, it is also widely used in other military departments.
For example, it has been applied to penetration seal rings, torpedo shells, torpedo launchers on naval submarines,
and the charge caps, wind caps, artillery warheads, cartridges and combustion chamber tubes of rifle grenades, armor-piercing shells, anti-tank rockets and other weapons.
It can also process ¦Õ (101~305) x50mm gun barrels. These products are large in quantity and wide in scope.
In addition, radar reflecting parabolic antennas can also be processed by spinning.
