A Large High-Speed Thread Rolling Machine with 30° inclined feeding, capable of producing screws up to 38 mm in length and 3–5 mm in diameter, operates on the principle of cold forming or thread rolling. This process involves shaping threads through plastic deformation rather than cutting, resulting in stronger and more precise threads.
