Titanium made by spinning

The enhanced howitzer barrel M77 light 155mm howitzer (LW155) is a firearm used to update the outdated steel fortified M98155m howitzer, which was used in the US Marine Corps and the Army. The L15 cradle barrel can support the barrel system and the anti-seating system. It is a component used by the National Center for Improved Metal Processing Technology (NCEMT) to use T-6A4V to improve performance. NCEMT is trying to determine a processing method for the barrel. In order to reduce costs and produce less waste than the current extrusion process.

NCEMT decided to use a new process called spinning. The Dynamic Machine Works (DMW) developed a spinning process to manufacture these barrels. As a result, DMW produced the largest spinning T-6A-4V barrel that has never been seen before, with a diameter of 142.

cm, length 183cm.

Spinning is a cold forming process that can manufacture hollow cylinders with precise dimensions. Due to its high accuracy, this process has been widely used in aerospace and military cylindrical components. During the spinning process, a thick-walled T-6A-4V alloy cylinder is rotated around a rotating ejector rod by means of a rotating pressure roller until it reaches the required size. Because almost 100% of the raw materials are retained, the spinning method greatly reduces the waste generated by expensive alloys. Based on the success of the process, it is expected that the process can be used in other weapon systems
