The video shows a metal rod being shaped into a cylindrical form. The rod is then placed into a machine that spins it at a high speed. As the rod spins, a tool is used to carve a pattern into its surface, creating a series of ridges and grooves. The process is repeated several times, with the tool making deeper and more intricate carvings into the metal. The final result is a beautifully patterned metal rod, with a smooth and shiny surface.
