The large thread rolling machine with ZR 90° feeding is a high-performance, heavy-duty cold-forming system specifically engineered to produce external threads and gears on long cylindrical workpieces with high precision and efficiency.
This advanced machinery employs a cross-feeding mechanism, where two hardened roller dies are positioned perpendicular (at 90°) to the axis of the rotating blank. As the workpiece rotates, one die moves horizontally into engagement while the other remains stationary, applying controlled pressure to plastically deform the material into the desired thread or gear profile.
Unlike traditional machining methods that cut or grind away material, this cold-forming process preserves the material's grain structure, resulting in stronger, more durable components with superior surface finish.
Thread and Gear Rolling: Designed for both external thread and gear tooth forming.
ZR 90° Cross Feeding: Ensures even pressure distribution and precise profile formation.
Long-Length Processing: Capable of handling screw lengths from 100 mm to 300 mm, ideal for extended shafts and large fasteners.
Cold Forming Technology: Enhances mechanical properties such as fatigue resistance, tensile strength, and corrosion resistance.
