SJ-36 Type Diameter Reducing Machine
The SJ-36 diameter‑reducing machine is a non‑cutting machining device that offers high production efficiency, a simple process, ease of operation, material savings, and stable quality. It employs hydraulic technology to cold‑press and form the portion of round steel requiring diameter reduction by feeding it into a dedicated die cavity. This process significantly increases the density of the compressed section, thereby enhancing the material’s tensile strength, while maintaining its ductility and impact toughness. As a result, the strength of the threaded portion and the shank are uniform, eliminating the drawbacks associated with reduced tensile strength and impact toughness caused by lathe‑turned surface removal.
