Threading rolling machine R12-120Z

Key Advantages of the Yuhai R12-120Z Thread Rolling Machine

• Medium-Diameter Workpiece Capability — Designed for rolling threads on workpieces with a diameter of up to 14 mm and a maximum length of 120 mm, enabling the production of a wide range of fasteners including bolts, studs, self-tapping screws, and threaded rods.

• High Productivity — Delivers an output of 40–50 finished parts per minute depending on processing complexity and workpiece type, making the machine an efficient solution for serial fastener production.

• Powerful Drive System — Equipped with an electric motor that ensures stable operation when processing workpieces made from carbon and alloy steels.

• Cold Forming Technology — Forms threads through plastic deformation without chip removal, enhancing the strength of the threaded joint by densifying the metal structure and preserving the integrity of the material's grain fibers.

• Robust Die System — Utilizes a set of oversized precision thread rolling dies (movable die 210×40×120 mm and stationary die 190×40×120 mm), ensuring consistent thread profile quality and extended tool life.
